Adriana and Pablo are very good hosts who really look after you. The room is very comfortable and the flat is well situated close to Plaza de Italia on the D metro line. We took the Tienda Leon shuttle service to Aeroparque going into Buenos Aires but to go back to the airport since we were taking an early flight we took a taxi which wasn't a lot more expensive. Ask for the price before you set off.
A great place to stay in Buenos Aires!
