The apartment was somehow cleaned but not as well as you would expect for the cleaning fee we paid. It's in a building that seems to be rented to young groups that party and come home very late at night and wake everyone up. Impossible to sleep as the walls are very thin and we hear the noise from inside the building and outside in the street. The windows are paper-thin and shake when a truck or a motorbike passes by...
I certainly do not recommend during the weekends if you're in Barcelona to enjoy and rest... First and last time there.
