This was an excellent hotel all in all, the breakfast is excellent, wide range of continental things ..... you will not go hungry.
I cannot fault anything about the hotel, we arrived 3 hours early and were allowed to check in straight away.
City tax is 2.50 Euros (Jun 10) per person per night, out of that you get a bus / tram pass (However we drove everywhere)
The only thing I can fault is the town was definitely not for young couples ..... more retired couples / widowed couples. We only stayed for 2 nights and spent most of the time outside the immediate locality, so this did not affect us.
Free car parking on site, however the free WIFI is a T-Mobile hotspot (so not really for business users)
All in all an excellent hotel and had it been in a more younger couple location I would have given 5 stars. For the younger couple I would recommend Baden Baden.
