I spent a week in Barcelona with 4 friends and our stay was wonderful. Pau is really friendly and it's very easy to keep in touch with him. The apartment is not far from the underground and full equiped, with linen and towels for everyone. Pau left us some guides for the underground and city too, usually hard to find. Even if the building is definetly old, everything works with a little care. We strongly recommend Pau and his flat!
