I stayed here with my friend in the room designed for 3 people. The room was not very big but adequate, there were 1 single bed and 1 "double", wich was 2 singles pushed together. For us it was ok, but if you need a double bed, I think it will not be comfortable, because beds were sliding on the floor. Wardrobe was small for 3 people and had only 3 hangers. Our safe box wasn't working and our hair dryer was broken (but they gave us another one). My matress was very loud - I couldn't turn or get up without noise. We were on 2nd floor and our window faced someone's back yard.
On the plus side - it was near metro station (with we used a lot), short walk to Sagrada Familia or Torre Agbar. Bathroom was big and clean. Air conditioning and TV were working. Breakfast was not really cheap, but good with nice selection of simple breakfast food. Staff was friendly and accomodating.
So overall, there were some minor problems, but nothing critical. I think, it's a nice hotel and good value for money.
