My wife and I came by for our honeymoon. The Ewa & Pau's spot was perfectly located to get to most places in Barcelona. Our main issue was that the apartment next door was doing an intense remodel and we unexpectedly woke to hammering and drilling on the shared wall which is right next to the bed. I would ensure there is no more construction going on if before booking if you intend to go out and sleep in later than 11am. If the noise issue is gone then this place is a great spot near everything. As they do mention in the description this is on the 5th floor with no elevator.
