We had a lovely stay at the apartment which was clean, spacious and had a nice and homely feel with all the amenities your would want and need for a stay of a couple of days or even longer. Close enough to the city center and all the major sights. Easily accessible by subway or a stroll of close to half an hour. The only disadvantage was the lack of air condition in the bedrooms, especially the single bedrooms in front of the apartment. This made it, especially during the usually hot summers in Barcelona, almost impossible to sleep.
