I arrived in the evening. The ground floor room I received was freezing. Due to construction, it also had a huge dumpster right in front of my window. I turned on the AC. It was so weak that it could not heat the room in a few hours. I asked to change the room, but no room was available. I was told that the AC is not broken, but this is how it is in all rooms. Apparently, it was limited to save the hotel costs. You can ask a technician during the daytime to make it work better. It is the first time I am not happy with this hotel. The Staff was very nice, but could not solve the problem. They offered me a free breakfast, which was nice. Still, I prefer paying a few euros more and not freeze at night. It's kind of a basic request from a hotel...
