I stayed for 2 weeks whilst studying in Buenos Aires and have no complaints. The room is nice and private, basically had my own bathroom, the neighbourhood isn't completely "central" but is in easy walking distance of everything you need (pharmacies, supermarkets, subway etc) and was safe to walk around. Rogelio is a friendly guy who was really helpful during my stay, and I would recommend to other travellers, particularly those that are coming to study for example.
