Location, location, location. This is in the heart of San Telmo, close to buses, restaurants (atleast 50 of them!), San Telmo market, shops, groceries, etc.
The place was very nice too. Kitchen and bathroom were tiny but managable.
Cintia was a great host and she went above and beyond in helping us with anything we needed. Although she was in Netherlands and her mother was the local host, she was always reachable and was in touch with me from the day we booked the place. We definitely recommend this place for anyone looking for a cozy place to stay in the heart of the city.
We stayed there for a month and loved it.
