I spent two weeks at Lita's apartment and it was really perfect. She really looks after her guests, makes sure that everything is fine and is easy to talk to (if you speak Spanish). There are supermarkets nearby and you can easily get to other parts of Buenos Aires by using the Subte (underground) or one of the many buses. Or you walk up Cabildo road which is full of shops of every kind. Lita has great internet with a download speed of 25Mbps, no issues at all. The bathroom is shared with other AirBnB guests if the other room that Lita rents in her apartment is occupied.
