I was disgusted by having to pay over 500 euros for a two night stay in what was a mediocre hotel
The room was adequate, but had no window, just a skylight with a view of the sky.
The sofa had a dangerously broken arm, and the dead lock on the door did not work, which turned out to be an issue on my first night
I was followed by an unknown man to my room who was obviously high on drugs and kept banging on my door to be let in. I reported this to reception at the time, but saw no action on their part. The following morning I reported it again to reception only to discovered that the man had gained entry to fellow guests room.
In addition there was only hot water available for one of the three days I was there, making my stay in Berlin very uncomfortable in not being able to shower.
