We stayed at Javier's place for a few days in June - it was the perfect central location to explore Barcelona. It's very close to some major transportation hubs, and easy to walk to quite a few of the city's best neighborhoods. The apartment was cute and clean and offered everything we needed with the exception of wifi - unfortunately the ISP was having some kind of technical issue during our whole stay. However, Javier was always quick to respond when I reached out, and he followed up with the ISP at least once a day to provide me with a status update. It was out of his control - just bad luck for me! He offered a partial refund for the trouble, which was much appreciated. Even with the wifi issue, I would definitely stay here again since this was a temporary fluke and everything else was perfect.
