Maria went above and beyond the call of a great host. We arrived very late at night (close to 2am). She stayed up to let us in and gave us a lot of help and advice about using local transportation. She suggested an excellent bus tour of the city and even provided a map. She offered us coffee and croissants in the morning. She was very accommodating of our check out schedule, offering to store our bags as needed. Her apartment is in a fabulous location, a couple blocks from the Plaza de Mayo and Casa Rosada, as well as public transportation around town and to the airport. There are loads of restaurants and activities nearby. We found a great vegetarian restaurant within a couple blocks (Abuela Pan) and also a fantastic, reasonably priced tango show at cafe tortoni. We thoroughly enjoyed our time in Buenos Aires with Maria!
