This is a few km inland from the Rhein, but we found it ok using our satnav. It turned out to be a huge conference hotel, but they had a room or two spare, and it worked. The car park was full, but we found a space in the road not too far away.
Dinner in the restaurant was good, with a good wine list. Breakfast was buffet style, also good. Apart from the fact that we felt at times that we might be interloping on someone else's conference, it was fine for an overnight stay. We had a room at the back overlooking the meadows, which was quiet and comfortable.
