I stayed for a month on Andrea's place, on account of an internship at Hospital Muniz, quite close to the house. It was great for the internship, as the hospital was only a walking distance away.
The house is spacious and old. The only more significant problem is the area where it is located, an unpleasant area of ​​the city of Buenos Aires, a little more difficult to feel safe in the surroundings. Good price and super available hosts :)
