The only "down" of this room was the noisyness off the street. Part of it was because of construction work being done, which off course is just bad luck, but still, at night it was noisy. Maybe because we had to sleep with the window open because of the heat, BUT I bought ear plugs and the inconvenience was reduced a lot.
The room and bathroom were clean and nice.
Xavier was very helpful and available, and his recommandations were great, regarding restaurants as well as places to check out nearby.
The location made it really easy to go to to the Sant Jordy, and to come back late, at night after the concert. Going downtown is easy with frequent buses and the metro nearby.
We really enjoyed these 4 days in Barcelona and gladly recommand Xavier's Place.
