Xavi & Luna's apartment was the perfect place for us to stay. There were so many wonderful features but if I had to pick my top two, it would be the outside space and the location. The apartment is just a few blocks from the metro making it incredibly easy to get around Barcelona while staying in a quiet, residential neighborhood. In addition, it is within walking distance (maybe 15 - 20 minutes) to La Sagrada Familia and a fairly strenuous 15 minute up-hill walk to Parc Guell (there is also a free bus if you purchase tickets online in advance). The deck is the best place to sit back, relax and enjoy the Barcelona weather. I think the most distinguishing aspect of our stay here was Xavi's hospitality. He helped us set up taxi rides to and from the airport. He has maps marked with stores & restaurants in the neighborhood and he was always willing to help. Xavi really went above and beyond to ensure we had the best stay possible in Barcelona.
