Marta+Paul's place was BEAUTIFUL with an AMAZING location (It was just right beside La Rambla), and my boyfriend and I loved the place very much. It even has a cute patio that overlooks the street! However, it is not a very ideal place to stay if you are a light sleeper, as the trains rattling underground can cause quite a bit of commotion (It was negligible for us, but just a note for other travelers). In addition, the heating wasn't really working so the apartment was a little cold, but altogether, we had a very pleasant stay. The apartment was really clean as well, and the bed was very comfortable. Highly recommended!
