We stayed in Sven's apt for 5 days. Unfortunately, we didn't meet him, but his friend Lana was very helpful and Sven was very attentive by mail and phone. The apartment corresponds with the airbnb description and with the photos: very well located, spacious, luminous, well equipped and clean. The square (Plaça de La Virreina) in front it is really nice place to have a breakfast or a beer and tapas at night. In our opinion, Gracia is the best neighborhood to stay in Barcelona, very charming and cool. We dind't have any problem with the apartment and we really recommend!
