We enjoyed our stay at Pau's apartment. The location, between Sants and Hostafrancs near the Plaça d'Osca, is one of my favorite neighborhoods in Barcelona. The air conditioning is very good, the kitchen is pretty well equipped, and the apartment was mostly comfortable. We had an issue with the clothes washer, and Pau and his team were extremely good about communicating with us to get it fixed. Make sure you understand, however, that it's a third-floor walkup; that was okay for us, but it might not be for everyone. Also, some items in the apartment are just about at the end of their useful lives: the clothes washer really should be replaced and the shower should be replaced or recaulked.
