Never have I experienced this thin walls in a hotel, and my co-worker had the same in their room on diffrent floors.
This gave me a 1-star experience, as I could participate in the conversations of the neighbours next to me, and hear their television all the time.
The heating system was extreme, it blew out strong hot air, and added even more noise. This hotel didn't offer any peace and quiet at all, and I was exhausting to stay here during a businesstrip, or really any travel. I wouldn't recommend anyone going here, and I would not like to go again.
