I have stayed with Mary for 10 days. She is super nice, honest, helpful and very kind. The room is simple and clean, and a house has everything you need. This place has a perfect location, near the best transportation system, bus. metrobus, subway. The place is in the heart of San Telmo, the most historical and and bohemian part of Buenos Aires. And it is also very well priced. I definitely recommend to stay at this super nice place.
