Me and my wife stayed at this hotel in summer of 2006, let me tell it is the best hotel to stay. Rooms are very clean and the staff is very helpfullll. It is 10min away form the famouse and the most happening street "Las Ramblas"(walking). And make sure!!!! when you check in, you tell them that you want the room with window....
They also have High Speed internet connection for free on 9 or 10 floor. So you can surf the net for free.
