The Expat Vibe
🇨🇴 Medellin
The 'City of Eternal Spring' — a dramatically transformed city drawing thousands of digital nomads for its perfect climate, affordability, nightlife, and stunning mountain setting.
🇦🇷 Buenos Aires
South America's most European city — tango, steak, psychotherapy culture, and a vibrant, intellectual energy powered by a deeply affordable (if economically chaotic) peso.
Housing & Rentals
🇨🇴 Medellin
Short-term furnished Airbnbs absolutely dominate the expat market. Securing a local unfurnished lease requires a fiador (guarantor) and is very difficult for foreigners. Estrato system affects utility costs — higher estrato = higher bills.
Top neighborhoods: Laureles, Envigado, El Poblado, Belen
🇦🇷 Buenos Aires
Argentina's currency crisis makes USD go extremely far — but also creates chaos. Most landlords demand payment in USD cash (blue dollar rate). Short-term rentals are common. Formal leases require a 'garantia propietaria' (property guarantee) which is nearly impossible for foreigners — use Airbnb or short-term contracts.
Top neighborhoods: Palermo (Soho/Hollywood), Recoleta, San Telmo, Belgrano
Getting Around
🇨🇴 Medellin
The Metro is the pride of the city, including cable cars (Metrocable) into steep hillside barrios. Uber is technically illegal but universally used via InDrive and DiDi. City is in a valley — expect traffic.
🇦🇷 Buenos Aires
Subte (metro) is ancient but functional. Colectivos (buses) cover the entire city and are incredibly cheap. SUBE card is mandatory for all transit. Taxis/Uber are extremely affordable. The city is flat and bikeable.
Cost of Living Details
🇨🇴 Medellin
Extremely affordable. A couple can live very comfortably on $2,000-3,000/mo including rent. Menu del dia (lunch special) at local restaurants costs $3-5. Craft beer scene is growing — $2-4/pint.
🇦🇷 Buenos Aires
One of the cheapest major cities in the world for USD earners (due to favorable exchange rates). A couple can live excellently on $1,500-2,500/mo. A premium steak dinner with wine costs $15-25. Cafe culture is central — cortados cost $1-2.
Climate & Weather
🇨🇴 Medellin
Eternal spring — 22-28°C year-round at 1,495m elevation. Two 'rainy seasons' (March-May, September-November) bring afternoon showers. Never need AC or heating. UV is intense at altitude — always wear sunscreen.
🇦🇷 Buenos Aires
Humid subtropical. Hot summers (Dec-Feb, 30-38°C) and mild winters (Jun-Aug, 8-16°C). The 'sudestada' (southeast wind) brings extended gray, rainy periods. Spring and autumn are ideal.
Food & Dining
🇨🇴 Medellin
Bandeja paisa (the enormous traditional platter) at Hacienda or Mondongos. Arepas at Arepas Mia. Empanadas from any corner street vendor ($0.30 each). The food court at Centro Comercial Santa Fe has surprisingly good, cheap options. For fine dining, Carmen and El Cielo are world-class.
🇦🇷 Buenos Aires
Steak at Don Julio (book weeks ahead), pizza at Guerrin or El Cuartito, empanadas at El Sanjuanino. Sunday market at San Telmo for choripan (chorizo sandwich). Ice cream (helado) culture rivals Italy — Rapanui and Cadore are top picks. Cafe Tortoni for the classic Buenos Aires coffee experience.
Insider Tips
🇨🇴 Medellin
Live in Laureles, not El Poblado. Laureles is more authentically Colombian, cheaper, flatter for walking, has better food, and fewer tourist-trap prices. El Poblado has become an expat bubble with inflated prices. Also, learn basic Spanish — English is far less spoken than in Mexico City.
🇦🇷 Buenos Aires
The official exchange rate and the 'blue dollar' (parallel/informal rate) differ dramatically — sometimes 2x. Always exchange USD at 'cuevas' (informal exchange houses) in the financial district or use Western Union for the best rate. Never exchange at a bank or airport. This single hack effectively halves your cost of living.
