We stayed at Juan and Nina's apartment from 2-6 Dec, as well as 13-14 Dec. It was our best Airbnb stay to date. The apartment provided everything that we needed. The location was ideal as it was central to everywhere in Barcelona, with a metro just a few minutes walk away, and one stop to Passeig de Garcia. But I think what made the stay most memorable was Juan and Nina. It was their attention to details (as we arrived late at night, buying a big bottle of water for us as water in Barcelona is not really potable and leaving a chocolate for us to eat), as well as their attentiveness to everything. They helped us arrange all our transfers, they told us where to go, tell us how to get there. Staying in their apartment was like having friends in Barcelona. You can ask them anything and they respond almost immediately (I think the only time they didn't was when they were asleep!). They even helped us take delivery of our portable wifi device before we arrive. When I was in Barcelona, they reply to all my text messages immediately when I needed help. Perhaps, the only one complain if we even have, is that the bathroom often gets wet because the when we bathe, it splashes to the floor outside of the bath area. This is perhaps due to the glass panel not being able to block the water effectively. Also, the shower in the master bedroom does not sit properly on its holder. But these "negatives" were really small compared to what we got from them. If one had wanted a "perfect" apartment, one should have stayed in a hotel. What makes Airbnb different is that you are staying with a host that acts like your friend. Juan and Nina have been the perfect host for us. If you are going Barcelona, you should definitely stay in their apartment.
