It was a bad experience. A very small room for a lot of money. Half of the room is (23 sq m advertised) is occupied by bathroom. Shower leaks Berln, flooding the living space. It is necessary to clean up the water after the shower. The room is dirty. Hair and dust in the bathroom and near the small bed.
The large bed is comfortable, the other beds are very uncomfortable.
We spent the night there and canceled our reservation, it was difficult to get our money back.
Just one thing was good is self check-in.
