We've spent about a week in Laia and Sergio's apartment and had a great and relaxing week in Barcelona. The location is great, close to many touristic points, shops, a beautiful green market, and has a good public transport connection. The apartment is great, very specious and has everything you may need. Laia and Sergio were great hosts, very quick to reply to any questions and very helpful with advises. I would definitely recommend the stay in their apartment.
