Antonio's apartment is the best one I have ever reserved with airbnb. Roberto greeted us at the front door at Antonio's absence. He was extremely patient and helpful. Besides showed us around the apartment, he advised us where to go and the location of major attractions, recommended us a tapa restaurant, with which we immediately felt in love with Barcelona.
The location is unbeatable. We took taxi most of time because we wanted to avoid pickpocket in the metro, and it only took a few minutes to go any places. Casa batllo, casa mila and other Gaudi's works are only minutes-walk. Shopping is at doorstep, and there are just so many nice restaurants nearby. Barcelona is even nicer than we have imagined and I am planning to return.
