This is a very good hotel if what you're after is a small, simple, "all I want is a bed" hotel. The single-person rooms are small, but clean and have their own showers.
The wifi didn't work on the first night but worked after and was steady and fast. There's a TV in the room, though you cannot connect your computer to it (the input is blocked)
The people at the reception speak English too if you don't speak German.
