Very safe neighbourhood even very late at night. Subway station Line D is on Santa Fe avenue, about 10-15 min walk from the apartment. Many places to get groceries, fruits and wine. Gustave is very thoughtful to leave is shopping bag for groceries since you have to bring your own and to arrange transportation for the airport. Bring lots of cash since many places do not take credit or only take Visa, however all of the grocery stores even little ones take credit card. Banking system is not very developed so look for EB sign for the ATM machines. Buy SUBE card for metro and buses. Bus #29 is very close to the apartment will take you through the city center to San Telmo and La Boca neighbourhoods. Taxis are cheap very safe late at night since metro closes early at around 10:30 at night. We loved it here and Gus is a great host, very fast to reply. Will definitely come to Buenos Aires-the land of alfajores, empanadas, great history and very nice, polite people!
