Pepe was an excellent host-helpful and accommodating. Since our flight was late in the evening he offered us to leave our luggage in the apartment all day, which really made things much easier. As for the apartment, it is a 5 min walk from the Back de Roda metro station and next to many grocery stores and local taverns-definitely a great base for exploring the city. One thing to have in mind though is that, as most of other places in Barcelona, there is no AC, which was not a problem for us since it was already September but might be an issue in the middle of the summer for some.
Overall-it was a great experience and I highly recommend Pepe's place!
