I enjoyed our stay at Joseph's apartment in Barcelona. Its location is perfect. It locates in an residential area (so not full of tourists), but a main street (feel safer and convenient). We could walk to Camp Nou for the tour and Barca game. And we could easily take buses/metro to the beaches and do city sightseeing.
Inside the apartment it is roomy for a family of 4 (2 adults and 2 kids). Love the master-bed as it's so firm that my wife and I could sleep well (better than 4 stars hotel beds). I highly recommend his place.
