Things to do
Buenos Aires is best read district by district: Microcentro around Plaza de Mayo, San Telmo with its antique shops, Palermo with its parks and Recoleta with its cemetery and museums. The subte links them in straight lines, and taxis cover the longer hops.
Plaza de Mayo and San Telmo
Start at the Casa Rosada and the Cabildo on Plaza de Mayo, then follow Avenida de Mayo towards the Congress building. On Sundays turn into San Telmo for the antiques fair on Plaza Dorrego.
Recoleta
The Recoleta Cemetery, with its marble vaults and Eva Perón's tomb, stands beside the Pilar church. Walk on to the National Museum of Fine Arts and the parks along Avenida del Libertador for the rest of the afternoon.
The parks of Palermo
The Palermo parks with the rose garden and the Japanese Garden stretch along Avenida del Libertador. Browse the shops around Plaza Serrano in Palermo Soho and have dinner on Gurruchaga.
Where to stay
San Telmo
San Telmo suits anyone who wants antique shops, tango bars and old apartment buildings around the corner. The Sunday fair fills the streets, yet the centre is walkable and a taxi to Palermo takes about twenty minutes.
Palermo
Palermo draws people for the parks, the cafés and wide streets that fill with restaurants at night. The district is large: Soho is busy, Hollywood quieter, and the centre is a metro or taxi ride away.
Recoleta
Recoleta works for quiet stays near the cemetery, the museums and the park. It costs more than San Telmo, but the streets are green and calm, and the shops and cafés keep a high standard.
Getting to and around Buenos Aires
Buses and taxis run from Ezeiza international airport to the city, a drive of roughly an hour; domestic flights land at Aeroparque beside Palermo. Within the city the subte and the colectivo buses carry most people, and metro tickets go on a SUBE card. The centre is compact, but the blocks are long, so taxis help in the evening.
