I stayed at Maria's place for two weeks in November 2015 whilst working in Buenos Aires. The flat was perfect. It was comfortable, well equipped, and quiet (with sunny top floor terrace high above the street). All the shops, bars and restaurants you need nearby. It is right next to Plaza Italia, which had all the buses I needed to get about, as well as being on the D line of the metro which heads downtown. Nice parks beyond that; and Palermo in the opposite direction; both an easy stroll. I recommend it.
