The flat looks just like on the pictures. It is not huge, but two separate bedrooms were a great convenience. We were a group of 3, but it fits for 2 couples as well.
The smell described in other opinions ( only in the building entrance) sometimes appears, but it is irrelevant.
Safe neighberhood, the most interesting places within walking distance. Only few minutes to the metro station and bus stop.
Near the house bigger and smaller shops, a small bakery, and pincho bars on Carrer de Blai (Pincho J highly recommended).
I hope to visit Barcelona and Vincent again.
