Montse's place is like a home away from home in Barcelona. It is up on the 5th floor with lovely breezes and views across roof tops. We had space to relax as a family of four. Her kitchen is well set up abd easy to find everything.
The location os excellent, we were able to walk to see many of the sights of Barcelona including short walk to Sagrada Familia, Passeig de Gracia (main shopping street and Casa Battlo and La Padrera). There are supermarkets and cafés close by, and a few different metro stops to choose from. We were easily able to take metro from Sants when we arrived .
I would highly recommend this apartment and would definitely stay again if I'm lucky enough to return.
