The hotel is definitely of international level, is clean and has a nice view of the town if you ask for a high floor room.
The room was spacious with a nice desk and sitting chair. The in-room restaurant service is ok and fairly priced. The top floor has a nice sauna, showers and nice relaxation area with a good view of the town. The staff was very professional and helpful to solve a booking problem with the Ramada web site. I can recommend this hotel for a business stop in Kassel.

My husband and I spent 2 nights while visiting Kassel to see the art exhibits at Dokumenta XII. The location on a tram line between the Bad Wilhelmshohe Bahnhof and downtown was excellent. We had a gigantic suite on the top floor with a great view. But the room was not cleaned at all even though we were gone from 10:00 in the morning until 5:00 in the afternoon. The service at the restaurant was extremely slow and there were clouds of flying insects around the salad bar. All in all, I would not stay at this hotel again nor recommend it to anyone.

Great view from the 8th floor but nothing remarkable about this place. It seems to be in a suburb with no restaurants near. Staff were friendly and helpful but the food was very very average. Had to send back two bottles of "house" wine as it was so bad!
