Sofia's apartment was more than we had expected. We had a wonderful time exploring Barcelona based in her apartment. Great location, easy travel links (the Sagrada Familia was only a 10 minute walk) and the apartment was right next to a good metro line. Sofia was very welcoming and gave us some great advice and some great recommendations for food in the city. My one note would be for light sleepers, as you can hear the rumble of the metro train, but this did not bother us too much.
