I needed a room for only one day, and I got there and they had a room for me available, although they were pretty much full. The lobby looks really good, golden railings and red carpets. The staff was very friendly, and helpful. At first I had some problems with my room key, and had to go all they way down to the lobby again to have it fixed, that pretty much sums up my negative experience of this hotel :)
The room was absolutely beautiful, and the bathroom was excellent. When I came into the room there was a complimentary water bottle waiting for me, and on the TV screen, they had a personalized message to me. It was very nice. The beds were fine, but with the same pillows that I hate so much, and are basically in every hotel in Germany.
They do have a parking garage, but it is not very big, and if there are many guests it is probably full. But there is a reasonable parkhous about 500 meters away.
