This is a historic facility that has 3 pools, of which only one is available for public swim the…read moreother two are only for swim lessons and swim teams. I went there the other day and was blown away by this hidden gem. I used the sauna (it was mixed that day, male & female) and steam room, I'm rarely impressed but the staff as well as the service was fantastic, I also used the massage services from a well trained therapist that was amazing let alone the price 20 Euros for 30 minutes. This facility run by the city of Mannheim is a must for everyone looking for a swim, massage or sauna let alone the historic architecture.
