Few cities pack in this much energy for so little money. Buenos Aires mixes grand boulevards and belle-époque façades with a restless creative scene, and its universities draw exchange students from across the globe. The rhythm is addictive: long lunches, dinners after nine, and a nightlife that genuinely never quits.

• Spanish immersion in a city where you'll actually be forced to use it, plus a huge international student crowd to lean on
• One of the world's great value destinations right now, thanks to the favourable exchange rate

Porteños are sociable night owls, so plan for late starts. Expect asado gatherings on rooftops, milongas where you can learn tango for free, and boliches in Palermo and Costanera that only fill up around 2am. Football is a religion, and catching a Boca or River match is a rite of passage.

• Join a free tango class at La Catedral or a Sunday milonga in Plaza Dorrego, San Telmo
• Ask the Buenos Aires Studcasa group where the week's language exchanges (intercambios) are happening around Palermo and Villa Crespo
• Grab standing-room tickets to a Primera División match, or watch at a neighbourhood bar if it sells out

Argentina is one of the cheapest places you'll ever study, though prices shift with inflation. Budget roughly €500–800 a month including a room, and you'll still eat out and go dancing often. The catch is the exchange rate: bring US dollars in cash and change them via Western Union or the blue market rather than the official bank rate, which can halve your money.

• Load a SUBE card for transport, where single subte and bus rides cost only a few hundred pesos
• Bring crisp US dollar bills and use Western Union for near-blue rates paid straight to a local account
• Eat a full menú del día lunch for a couple of euros; a parrilla dinner with wine rarely breaks the bank

Most exchange students rent a room in a shared flat, often paid in US dollars month to month, since long leases demand a local guarantor (garantía). Palermo, Recoleta, Belgrano and Villa Crespo are the safe, well-connected favourites. Never sign anything before seeing it in person.

• Search ComparteDepto and Facebook groups like 'Alquiler temporal Buenos Aires' for shared rooms
• Budget rooms in Palermo or Belgrano typically run US$250–450 a month, bills often included
• Post in the Buenos Aires Studcasa group before you land, departing exchange students frequently pass on their rooms

The city is flat, grid-planned and easy to read. Six Subte lines (A to E plus H) cover the centre, backed by a dense colectivo bus network that runs all night, all tapped with one SUBE card. Ecobici offers free short bike hires, and the Cabify app is cheap for late nights.

• Buy and top up a SUBE card at any kiosco or station, it's the only way to pay for buses and the subte
• Use the free Ecobici public bikes for Palermo's parks, registering with your passport in the app
• Take Cabify or a street taxi rather than walking home alone after 1am

Buenos Aires is Argentina's academic heart. The vast, free Universidad de Buenos Aires (UBA) sprawls across the city, while private institutions like Universidad Torcuato Di Tella, Universidad de San Andrés, UCA and UADE run more structured exchange programmes. Terms run March to July and August to December.

• UBA faculties are scattered citywide, so check which building (facultad) holds your classes
• Private universities like Di Tella and San Andrés offer courses in English and smaller classes if your Spanish is shaky

Rules depend heavily on your nationality. Many passport holders can enter visa-free as tourists for 90 days, and some students effectively study on that basis for a single semester, extending once if needed. Officially, longer stays require a student visa arranged through an Argentine consulate before you travel.

For the student visa you will typically need an acceptance letter, a criminal-record check, a birth certificate and consular legalisation, so start early because it is slow. Once in Argentina, student-visa holders register for temporary residence and get a local ID, the DNI. Always confirm the current requirements with the consulate for your country.

• Many nationalities: 90-day visa-free tourist entry
• Longer stays, student visa from an Argentine consulate
• Student visa needs an acceptance letter, police check and legalised documents
• On arrival with a student visa, register for temporary residence and a DNI

Life revolves around meat, pastry and mate. Sunday asado is sacred, empanadas and milanesa are everyday staples, and no coffee is complete without medialunas. You'll be handed a gourd of mate to share, so never refuse it and never stir the straw. Dinner starts at nine at the earliest.

• Eat at a classic parrilla like Don Julio, or a corner grill, for the full asado experience
• Wander the Sunday Feria de San Telmo for antiques, street tango and choripán
• Buy a mate gourd and a bag of yerba, sharing it is how friendships start here

Palermo is the student and nightlife magnet, split into leafy Soho and busier Hollywood. Recoleta is elegant and central, Belgrano leafy and calmer, San Telmo bohemian and historic, and Villa Crespo the cheaper, up-and-coming option right beside Palermo.

• Palermo Soho for cafés, bars and boutiques within walking distance of everything
• Villa Crespo for lower rents a block from Palermo's action
• Belgrano or Recoleta for quieter, safer streets and good transport

The flat Pampas and a good bus network make escapes easy. The Tigre delta is an hour by train for a day among the waterways, and Colonia del Sacramento in Uruguay is a quick ferry across the river. For bigger adventures, overnight buses reach Mendoza's vineyards and the Iguazú falls.

• Take the Mitre train from Retiro to Tigre (about an hour) and hire a kayak on the delta
• Ferry to Colonia del Sacramento, Uruguay, with Buquebus or Colonia Express in around 75 minutes
• Book a cama-suite overnight bus to Mendoza for wine country, or fly to Iguazú for the falls

The single biggest mistake is spending on a foreign card at the official rate, which loses you nearly half your money. Bring dollars, use Western Union or the blue market, and carry cash since many places still don't take cards. Adjust to the clock too, because nothing social happens early.

• Never pay by foreign card where you can pay cash from Western Union pesos, the difference is huge
• Download the BA Cómo Llego app for live bus and subte routes
• Keep your phone tucked away in crowds, especially around Retiro and La Boca at night
