We stayed in room 8, It's very nice and big, very well lit. The bathroom is well equipped and also big. We were very comfortable during our stay.
It has hermetic windows and you can hear no sound from the very crowded and noisy streets of Barcelona, we were able to rest and sleep wonderfully.
The AA and the mini-fridge stopped working on the second day, they went to fix them but unfortunately, nothing changed. Other than that, I would recommend this place and would rent it again for my next stay :)
