Your First Week in Buenos Aires: A Seven-Day Checklist

The first week in Buenos Aires is easier when the first address is temporary. Two to four weeks in a cancellable flat gives you somewhere to land and enough time to inspect a longer-term home in daylight. A working phone, a UK card and a little peso cash will get you through the first errands; residence paperwork can wait until you have found your bearings.

In September 2026 the official exchange rate is about ARS 1,545 per US$, and UK cards convert close to it. There is little reason to spend arrival day hunting for an informal exchange. The more useful question is whether you can reach your flat, get through its door and pay for dinner.

Before you fly: make the first address work

Save the flat's street address and cross-street, your host's WhatsApp number and an offline map. Agree on check-in time and how late keys will be handed over; if you have heavy luggage, check lift access and whether the building has a porter. A street and cross-street will help a driver more than a UK-style postcode. Browse furnished flats to compare layouts and areas, but make the longer-term decision after a viewing and a full-cost quote.

While you have dependable Wi-Fi, set up WhatsApp, maps, Uber or Cabify and your UK banking app. An eSIM can provide data as soon as you land; roaming may do the same if you know its charge. Keep your UK SIM active until bank security codes work another way, and carry a second payment card separately from the first. Buenos Aires stays on UTC−3 all year, three hours behind Britain in winter and four behind during British summer time.

Day 1: from the airport to a functioning flat

From Ezeiza, the international airport, an authorised airport transfer or a ride arranged through your accommodation keeps the luggage leg simple. Aeroparque is much closer to the centre, though neither arrival calls for learning a bus route with bags. For an app ride, match the car and plate before boarding and decline unsolicited rides inside the terminal. Weekday commuting peaks can lengthen the journey.

At the flat, photograph its condition and try the lock, Wi-Fi, hot water and air conditioning or heating before unpacking. Keep the exact building address, flat number and entry code in your phone. A failed essential service is easier to resolve when reported in the booking channel straight away rather than left as a verbal promise.

If your eSIM works, a shop visit can wait. Otherwise, a Personal, Claro or Movistar official shop can help with a prepaid line, or prepago: take your passport and have the staff activate and test data and WhatsApp there. Your handset needs to be unlocked and compatible with the local network. Contract accounts can require Argentine identity and payment details, whereas a tourist can use prepaid data; the mobile-plan guide sets out those options.

A small grocery purchase will tell you whether your UK card works. When a terminal offers ARS or GBP, choose ARS and let your card network convert it. A modest peso reserve covers a kiosk, a taxi or a terminal outage. Keep your passport secure and a photograph of its identity page and entry record for reference, though the photograph is not official ID.

Save the CABA emergency numbers while you have a quiet moment: 911 for police, 107 for SAME ambulance and 100 for fire. An operator will need your street, nearest cross-street, barrio (neighbourhood) and floor or flat number. If symptoms are serious, getting care comes before sorting out insurance.

Day 2: the payments and journeys you will actually use

UK contactless cards work in many shops and restaurants, but some small sellers take cash or an Argentine QR payment. Mercado Pago, the widely used QR app, is different from Apple Pay; an account or particular features may require Argentine identification or a local payment method. A first meal should not depend on opening it.

The official SUBE website or app lists sellers and service centres; stock at an individual kiosk varies. A simple ‘¿Tenés SUBE?’ asks whether the seller has a card. Payment methods, the card price and fares can change, so the displayed price matters more than an old quote. An initial ARS 10,000, about US$6.50 at the September 2026 reference rate, is an illustrative top-up for several journeys, neither the price of the card nor a promise of a week's fares. An online or app top-up may need to be credited to the physical card as SUBE instructs.

A short daylight trip gives the network some shape. Maps or the official BA Cómo Llego planner show the line, stop and direction; check a bus's number and destination with the driver because several routes can share a street. Tap the card where required at entry. Public transport in Buenos Aires compares the bus, subte and train in more detail. Repeated small ATM withdrawals may cost more than one planned collection. Since currency controls for individuals were lifted in April 2025, swapping sterling for dollars to visit an informal dealer is not a necessary first-week errand.

Day 3: make the streets around your door usable

A loop from the flat to a supermarket, farmacia (pharmacy), subte stop or bus route tells you more than a city map. Notice the well-lit way home after dark. Día, Carrefour Express and Disco are common grocery options; shelf offers and payment-method discounts make the till receipt useful too. Argentine sockets commonly take Type I plugs rather than UK three-pin plugs, so a plug adaptor may be needed. A few meals' ingredients, drinking water if you prefer it and washing-up supplies can wait until you know what the host has provided.

Find a pharmacy you could reach when the nearest one is shut. The farmacia de turno is on out-of-hours duty, and the rota changes; pharmacies display lists or can tell you where to go. For repeat medication, original packaging and the active ingredient name will help when the British brand name is unfamiliar. Save the emergency and provider numbers for any health cover. Public hospitals can charge non-residents for non-emergency care under the 2025 rule; emergency care remains free. Healthcare in Buenos Aires has the longer explanation.

Small transactions are good Spanish practice. ‘¿Aceptan tarjeta?’ asks if a shop takes cards, ‘¿Cuánto sale?’ asks the price, and ‘Una recarga para la SUBE’ requests a top-up. British school Spanish often teaches tú, while locals commonly use vos. A clear address and a polite request will matter more in week one than a perfect accent.

Days 4 and 5: see the flat and test your working day

Once the immediate errands work, the housing search can become more specific. A morning and an evening walk show different sides of an area: Palermo Soho has restaurants and late activity that can mean noise; Belgrano offers residential streets and transport; Almagro and Caballito change the balance of price and access. The neighbourhood comparison helps connect those choices to a daily routine. Before you sign a lease, read renting a flat in Buenos Aires as a Brit.

A central one-bedroom averages about US$750 a month, roughly ARS 1.16 million at the September 2026 reference rate. A short furnished let may cost more than a longer lease. The monthly ceiling needs room for expensas (building charges), utilities, internet and possibly cleaning. During a viewing, mobile signal, water pressure, window condition and street noise are as consequential as the photographs; stairs or lift, daylight and the actual commute will decide whether the place works.

After the repeal of the 2020 rental law, lease length, currency and adjustment frequency are negotiated freely. The quote should set out rent currency, deposit, included costs, adjustment schedule, cancellation terms and inventory before money changes hands. Compare Buenos Aires rentals without paying an unverified stranger to hold an unseen flat.

A working day also starts outside the flat. A panadería sells bread and medialunas (small sweet pastries); a verdulería is a fruit and vegetable shop. Local shops may prefer cash or QR, while chains generally take cards. Prepared-food prices and delivery charges should be visible before an order is confirmed; PedidosYa is the local counterpart to Deliveroo. Knowing where to shop makes delivery an option rather than the default.

For UK hours, a 9am London call falls at 6am in Buenos Aires during UK winter and 5am during UK summer. A video call from the flat will show how well its internet supports that routine; a speed test, the outage-reporting process and a nearby second connection add context. A café can provide a change of scene if you buy something and mind your belongings, though sockets are not available at every table.

Days 6 and 7: build a routine, then count the cost

A repeatable activity gives week two a shape: a Spanish class, football, a gym session or an intercambio (language exchange). Learning Spanish in Buenos Aires takes the longer view. Hosts, neighbours and classes commonly coordinate through WhatsApp, so the exact meeting point and time may arrive there. Dinner often starts later than in Britain, but your whole schedule need not change in a week. With children, a nearby playground, pharmacy and trial school or nursery route may be more useful than another flat viewing. Illness or an unsafe situation takes precedence over any day-by-day plan.

Consider two British adults booking 21 nights at an illustrative US$55 a night in a furnished flat. 21 × US$55 = US$1,155, about ARS 1,784,475 at the September 2026 reference rate, before cleaning or card charges. Their ARS 150,000 cash contingency (about US$97) and ARS 10,000 initial load (about US$6.50) on each of two SUBE cards cover other immediate needs. That 21-night rent alone exceeds the roughly US$750 monthly central one-bedroom benchmark. By day four, they can compare the flat's internet, cancellation terms and transport before choosing to extend it.

A broader single-person monthly budget is about US$1,300-1,900 in September 2026, roughly ARS 2.01-2.94 million at the reference rate. It is a planning figure, not a week's spending allowance. Accommodation, food, journeys, mobile data and health costs recorded from your own first week will make a better comparison with life in Britain. A local prepaga, a private medical plan more like Bupa than the NHS, can cost around US$130-870 per month at age 30, depending on tier; an older person's quote may differ.

The first week can establish a home base without settling a lease or a residence application. A British visitor's initial visa-free allowance is 90 days, which is not permission to work or remain indefinitely. For appointments, residence and the DNI (national identity document), paperwork after arrival is the next practical step. A flat whose costs and commute you have actually tested is a sounder choice than one secured in haste from abroad.
