The place is lovely and really close to subways and busses stop. The San Telmo Barrio is really great to stay, with plenty of places to visit and a really good cuisine, and both Teresa and Mica were kind and responsive.
The only things you may need to be aware is, the roof makes the place really hot when there is sunny days and, if you're tall like me (1.95m), the shower will be a bit annoying.
