Pleasant, comfortable hotel centrally located in Badenweiler by the thermal baths and park. The hotel's own wellness center is chic and inviting. Nice room, good breakfast. I felt that I was in good hands.

Highly recommended

Top food! **** Pool / SPA available, sufficient for us, but not particularly large. *** Booking a massage by e-mail is quick and easy! **** Room 276 needs an update! The ceiling was half painted. **
