Great location, being a 3-minute walk from Segrada Familia, which has a tube station. You can have a pleasant walk to Las Rambla in about 20-25 minutes.
Only gave it 4 stars because there was a situation where someone had tried to break into the apartment room whilst we were in there, the door hinge was nearly broken off. The receptionist was available and sent a technician to fix the door promptly (24-hour service). The room had 2 front doors locked, but we still felt a little threatened.
But other than that, was a great stay in Barcelona. Recommended!
