My wife and I have stayed at the Hotel Rheingold three times. The hotel features good size, clean rooms, with excellent amenities. It is located one block from the train station but is not noisy. The price is reasonable, the breakfast excellent. Highly recommended. The Virtual Tourist price guide is a little misleading: it requests an amount per person, not per room -- or room size. The price for a double room (two beds, very comfortable) at the Rheingold is around 100 euros.
