The check in was very efficient and as described in the informative message from Pau. Best thing about the place is the location. Close from metro station Parallel, 10 mins walking from the center. Value for money accommodation for sure. We were with a local person, so did not follow the touristic suggestions from Pau, but they can be very helpful. The airco was a life saver, as we really needed it on the warm days (there are three units, two in the bedrooms and one in the living room.
The place was smaller than expected based on the impression from the pictures posted on the advertisement on AirBnB. The elevator duct, which is next to the kitchen sink, smelled bad and was at times annoying.
All in all, a value for money accommodation, at an excellent location in Barcelona.
