Xabier's apartment is ideally situated, within walking distance from the airport bus stopping at Placa de Catalunya and with many metro and bus lines within minutes of reach. I also thought it was very convenient that thre's a small supermarket and two cafés where to get breakfast just next to the building. Xabier was very accomodating and always responded very quickly. One thing I would point out is that the room is oriented to the front street which is very busy so you should definitely bring earplugs and be okay with trafic noise.
