Nice hotel with very good servis in nice small city. Rooms are quite big, modern equiped, beds have very good mattresses. Room service is very good, breakfasts are more than sufficient. The hotel restaurant with bar is nice, located in basement (like place where the breakfasts are served), you can't be wrong when you chose this restaurant for evening
If you need access to WiFi, beware of hotel rooms 231-237, 331-337, 431-437 - even WiFi is here, practically is not useable because unstable connection and very low speed. WiFi at conference rooms and around reception is very good.
BTW. you can buy phone card for your mobile in shops like REWE ( handykarten T-Mobile, Vodafone,...), Aldi,...
