It was a very fine hotel. I stayed one night prior to a flight from Dusseldorf airport. It seemed to me that this hotel is kind of a higher class business hotel but was already a little older. Upper floors were business rooms and one needed a key to get there with the elevator, which I didn't have. I could imagine that they were recently remodeled.
No free shuttle to the airport, so this is a disadvantage. Room was clean, had a TV, and a bath tube. Shower was nice and strong. Strangely, the trash cans did not have a trash bag in it, they were, however, clean and empty.
