My parents and another couple, friends of them, spent two nights at Isabel's apartment.
They found there an extremely beautiful and clean place, with everything (and more) they needed for their stay. They highly appreciated the position, perfect in its quietness and closeness to city center and metro. Moreover, they have been extremely satisfied by the kindness of Isabel, who was available to help them in all their needs.
They strongly recommend it and we will consider for sure Isabel's apartment as our first choice for our next stays in Barcellona.
