Just in front of Hauptbahnhof. It takes 10-15 minutes walk to old city center, or 5 minutes by bus.
The room has enough space so to say comfortable, and well organized. Heating system works properly.
Breakfast buffet is with good enough selection. Because I had to left the hotel early in the morning, before breakfast, the hotel prepared lunch (breakfast) box.
I can say stay in the hotel is worth for the money.
