We had a very nice stay in Barcelona and the apartment was part of that positive experience. It is located one floor above a hostel in the center of the city. There was no problem sharing the kitchen and the two bathrooms (one has a shower) with the other residents on the floor, and the common areas were well equipped. We also liked the quick and easy communication with our host, Tadeu.
We would love to come here again on our next visit to Barcelona.
