The place is in a great central location, has many small grocers and large grocery stores around, a metro station and many bus routes. Within a very short walking distance, is an abundance of bars, restaurants and cafes (Palermo) - very safe at night. There is also a popular Argentinian tango place very close.
The place is very pretty and neat with a nice balcony to have breakfast or a glass of wine. There are washers and dryers inside the building, which was convenient.
Ricardo is a great host, very quick in responses and very communicative. He has provided us with many recommendations and local tips (including safe taxis, how to exchange money, food to try etc.). We really enjoyed our time in BA.
