Dive Into a World of Well-Being
From the moment you step inside our Aqua Spa, the outside world fades into the background.
There are never more guests than what feels right. Let the water and the calm of the space embrace you — you’ll feel your shoulders relax and your senses awaken. When you leave us, flowers will smell sweeter, wine will taste better, and you will feel recharged and renewed.
This is salus per aqua — health through water — in the truest, original sense of the word spa.

You’ll receive your own iPad, loaded with magazines and guided meditations,

designed to soothe both body and soul.
