I can't recommend Javier's apartment highly enough; our family stayed here for a week and loved it! The apartment is in a lovely lovely residential area with lots of great restaurants and is an easy walk to some of Barcelona's tourist attractions. Javier was incredibly helpful, and couldn't do enough to ensure our stay was as pleasant as possible. The square the apartment faces onto was a hit with our two boys; lots of other little ones to run around with, and great pizza and gelato shops to boot.
