Proximity to the spa.
Horrible customer service, as in none. You cannot check into the hotel from 2 pm to 5:30 pm. Upon arrival there is no note, sign, or any form of communication letting the guest know check in times. The doors are locked and no one answers the phone. The owner is slow, rude, and uncompromising in other words; mean. It is your responsibility as the paying guest to read the rules prior to and immediately upon arrival, know the house rules, and adhere to them. The breakfast is one of the most minuscule I've experienced in Europe. We visit Bad Wildbad often and will never stay at this property again!
Good, clean rooms in the center of Bad Wildbad. Good parking facilities. Nice atmosphere. Simple but adequate restaurant
