The pictures show the apartement really well. Apartement is really nice and just right for two or three persons - since there is an extra bed. It's only 10 minutes walking distance from barcelona main station where a train from the airport stopps every 30 minutes. The whole area is very nice, with many tapas-bars around. The underground-station is just around the corner so you can reach all barcelona-destinations in no time.
Everything in the apartement worked well and we knew whom we could contact if we had any questions - which we didn't. We stayed for 3 nights and would stay at the same place if we came back to Barcelona.
