This is the worst hotel I think I've ever stayed at. The AC did not work, so our room was probably 80 at night, and we were told by the manager that the AC was working properly, but it was not very powerful. Because it was so hot in the room I did not sleep well and ended up getting sick so for most of my trip to Germany I was sick.
The only good things about this hotel were the breakfast was good and the location was good, across from Olympic park.
When we checked out, the staff asked me if our stay was OK, and I said it was not. She ignored my response, probably because she had heard it so often.
