We stayed in the part of the hotel that was once a monastery. Everything was new and modern. Only hint of the old times was an occasional floor board (under new, quality carpet) creaking, I am OK with that 100%. Outside high temp was around 70 F, and a little too warm inside sometimes. AC would have been nice, but I overheard someone say it has to be turned on for the entire building, cannot have heat vs. AC determined in each room. No AC vents, so if I heard correctly, the suggests chilled water. Not sure. Steam room not working while we were there, but sauna, cold water foot baths (could not seem to get hot water foot baths working), and 'brine grotto' were all fine. Near the sauna were a regular shower and a strong cold water shower. I like to heat up in the sauna and then gasp in the cold water shower, then do it again. Awesome! US visitors should be aware no swimsuits is standard in German saunas. For everyone. Not an issue over there. Reprogram your brain if needed so you are cool with local customs. Do sit on your towel. Very important. Regular indoor pool big enough for lap swimming. 104 lengths == 1600 m. Watch out for ignorant kids swimming in front of you. Geo thermal pool is comfortably warm. Parking garage is tight by US standards, but comfortable, modern and clean by EU standards. We had no problem parking at any time during the week, but the lot looked full when we pulled out for touristing Easter Sunday morning. By our return that evening, lots of spaces open.
