 The only negative point is that if you wish to extend your stay for a few hours as we did because we had a flight late in the afternoon the cost per hour was a bit high approximately 10 15euros per hour But they provide storage for the luggage for free 
 We really enjoyed our stay in Barcelo Sants It was right outside the metro station actually above it and very close to the city center The hotel has a special design kind of spacial the room is very comfortable and through the large window the view is amazing In regards to the bed there are no words to describe The staff was very kind wiling to help us
