Dolors was a great host! The apartment is the same as on the photos and she is keeping it in a perfectly clean condition. She is very considerate to her guests, making sure she doesn't make too much noise to wake up the guests when she's going to work. She also gave us good advice about the surrounding area.
One thing to mention, that could be helpful to the future guests, is that near the apartment there are two bus lines: N6; and N16, operating the whole night even when the tube closes. So the location is perfect also for the people who like to stay out just a little longer.
We would definitely stay again at her place, if there was a chance in the future, and would recommend it to other guests too.
