My girlfriend and I had a great 3 night stay in Xavi's apartment.
The apartment itself was fantastic, the furniture in our room was basic but all very good quality and we certainly didn't want for anything. We didn't spend a huge amount of time in the communal kitchen or lounge but both were furnished to a high standard and very clean. The bathroom was large and clean. Unfortunately the hot water was working on and off while we stayed, but Xavi found an interim fix while waiting for it to be serviced and went out of his way to help out.
The location was fantastic, a minute walk to the Arc de Triomf and metro station and well within walking distance of lots of other landmarks. There were lots of great cafes for breakfast and lunch and brilliant restaurants for dinner within 5-10 minutes walk of the apartment.
While Xavi stays in the apartment it didn't feel like it as he stayed out of our way and let us enjoy the apartment. We had a great time, and would definitely stay in the apartment again!
