I recently stayed at a hotel in Berlin, Germany, with my kids for a three-day holiday, and it was a terrible experience due to the poor customer service. Despite leaving the door hanger for housekeeping, my room was never cleaned. When I informed the receptionist, I was told they only clean every other day.
The next day, the same issue occurred. My room remained messy, with wet and dirty towels piling up. I reported this to the receptionist again, but they didn't apologize or address the problem. The only thing they offered was a towel. To make matters worse, the room was filthy under the bed, with dust, someone else's socks, a lighter, tissues, and papers.
I do not recommend this hotel due to their lack of cleanliness and poor customer service.
