This place is simply incredible. They offer outstanding facilities. The nordic baths (which they call Water Circuit) overlook the river and the city, with an unobstructed view. It's a great place to go solo, with a couple of friends for a quiet evening or with a special someone. You can spend only a couple hours, but can easily spend a whole day if you choose to get various treatments (massage, body and facial treatments, manucures, pedicures) and have a nice meal including even wine or cocktails !
I had a 90 minutes therapeutic massage and was impressed by the very skilled therapist, and enjoyed the water circuit for a couple of hours before and after, enjoying the sunset over Montreal. It was simply fabulous.
