The breakfast is really nice, they even have a refrigerated room to keep cheese, salami and all fresh products; the Glas restaurant is way too expensive for what they offer, this is not definitely "gourmet", really small plates, neutral tastes, I would not recommend. The cleaning services are very good. The room had a stunning view of the Rhine. We had a permanent ironing board & iron in the room which we loved as we were travelling for business. The parking is at 36 euro per day - personally I think this is a high price for parking but it is kind of one way option as there is no cheap parking in the area. As an overall experience, I would go again, the staff was really kind.
