The place was clean and as described. Loved that it had a lift - don't miss this out if you are lugging heavy luggage!
It was very spacious for the two of us. With the additional bed rooms and two beds this place should fit four people very comfortably. Although we did not do any cooking, cooking and cleaning equipment were all there.
Location was also superb, a walking distance to the sites you would want to visit in Barcelona. Convenience shops were nearby. As it was in a good location, one would expect a fair bit of traffic noise, but with the airtight windows it was completely quiet.
