The flat was just as described. It was in the heart of one of the best neighborhoods in all Barcelona. Many of my favorite restaurants were less than three blocks away. Rambla de Catalunya is a pedestrian's dream. Tree-lined for most of its length, it was a pleasure to walk out the door of the building and then onto the promenade in a few steps.
I rented the flat and lived alone for most of the 9 weeks I was in Barcelona. So, plenty of room, and in fact, more than I needed.
But I did have a buddy visit for 2 weeks, and there was still plenty of room. The second and third bedrooms and 2nd bathroom were on the other side of the flat, so privacy was never an issue while my buddy was in town. The flat may feel a little cramped if you are a party of five, but even then, is should be just fine if your stay is not a long one like mine. ALso, the air conditioners kept the flat cool on those hot summer days and nights.
The only negative is that the building has an unfortunate odor that permeates the common space (foyer, stairways, elevator). I think it may be endemic to many buildings in Barcelona. My flat in Villa de Gracia in 2019 had a similar problem, except there, the odor permeated into the flat. Fortunately, that was not the case here.
