We had a lovely stay at Xavier's very nice, comfortable, and well-located apartment. The place is very spacious, well equipped with everything you might need, and extremely quiet - despite being in a very bustling neighbourhood. Gracia is one of the nicest parts of BCN and it's also easy (and very pleasant) to walk to the city centre along Passeig de Gracia or Rambla de Catalunya. Xavi was friendly, welcoming, and quick to respond.
