The apartment was very great, it was clean and neat, we had no problem at all, the terrace is amazing and so is the location of the apartment. The two metro lines near the apartment took us everywhere we wanted to go, they stop at every place a tourist wants to see. It is true that going up the stairs was exhausting, but as the time passed we got used to it and we have left fitter than we arrived.
Ricard was a helpful host, if we ever had a problem he answered immediatly. All in all we couldn't have chosen a better place to stay in Barcelona.
