We had delays upon arriving in Berlin, so the self check in was convenient. Unfortunately, we had an extremely poor experience after that.
There was a strong smell of smoke in the hall and flat which was unpleasant. The flat only had bedding available for one bed and it was covered with dirt/hair, and there was no alternative to replace it before having to sleep. There were stains on the carpet, furniture, curtains, and walls. We found rubbish and a cigarette butt left behind with the smoke alarm unscrewed from the ceiling in a drawer. There is no washer an dryer available in the room, rather it’s in a shared space downstairs.
There was no apology for the state of the room and we were given the option for a cleaner to come or to move to a new room. The second hotel room was in the same or worse condition.
The hotel was responsive and worked with us to adjust the dates of our reservation to check out the next day instead of our planned four days as we were not comfortable staying.
