First the good Point: The Hotel is located great right in the middle of the city. You get everywhere really fast.
BUT: The Hotel really need some improvements. We first got a room, in which the mattress was very saggy, the tap was crooked and the walls were dirty. We then asked for another room.
The lady at the reception then gave us another room, but made it clear this is only a „favour“ of her, as she was certain that the original room was totaly fine.
The new room was only slightly better, as the wallpaper was coming off the wall, the vent was full of cobwebs, there was a cigarette butt in the window. At night you could hear every noise from the hallway.
Overall, we can not recommend going to the hotel. Also because you can get much better hotels for the price, which are a bit outside. Since the local traffic in barcelona is super developed, that would have been the better approach in the aftermath.
