Gym & sauna A state-of-the-art gym with workout and body-building equipment is located in the basement of the HSG Alumni House. Next to it, a sauna with pools and a quiet zone invites you to come and relax. Depending on your requirements, you can select several programmes in the sauna: from the Finnish sauna at 85° to the very humid aroma bath with soothing fragrances. The team at the reception would be delighted to accept your booking. Use of the sauna and gym is included in the price of the room.
