To start with the apartment is fantastic and fully functional, either alone or with a family / young children. Cafe's / market shops nearby make it very convenient to stay. Depending on what your objective in Barcelona, central touristic areas are about 30 mins away by metro (15-20 mins walk to station and 5-10 mins train ride), or a 10 min taxi ride. Rosa was very helpful, flexible & always a call/message away which for non-Spanish speaking people made is very easy. I would recommend Rosa's apartment and more so her personal assistance & guidance!
