Me and my friend had a really nice stay at Maria's apartment. She replied quickly, exactly explained how to get to the place and there was no problems with late check in.
The room offered by Maria is in a great location - 2mins from the metro station, 7 mins walk to Sagrada Familia. Neighbourhood was safe, there's a plenty of bars, cafes and minimarkets near the place.
Maria's family was also super nice and hospitable.
Thanks a lot!
