We loved staying at Filippo's apartment in Gracia. The neighborhood is very lively, but the apartment faces out the back of the building, and is quiet and has a lovely terrace. Filippo is super responsive and when we had a small problem with the hot water, he was right on it to help us remedy the situation. He also recommended a nice paella place nearby, which we went to and enjoyed. This is a nice apartment in a great location - I would recommend to any friend or colleague considering a trip to BCN.
