We had a wonderful experience here. Our international flight landed quite early and Mariela was there to meet us right at 6am with the keys. The apartment itself is modern and very clean, with a lovely terrace. The Subte and bus stops are quite close as well. We also loved Olga's for coffee down the street. Belgrano is quieter than the super-hip Palermo neighborhood, but it's very safe, quiet and has plenty of cute coffee shops nearby.
