Treatments & Massages

Welcoming Treatment Rooms for a Timeless Moment

At the heart of the Bio Spa, five bright and soothing treatment rooms await your treatments:

— 3 individual treatment rooms
— 2 double treatment rooms

Enjoy a breathtaking view of the park and the avenue of century-old plane trees, with privileged access to the relaxation area.

Every detail has been designed for your comfort:
high-end heated massage tables, soundproof partitions, soft lighting, linen curtains, solid oak flooring…

After your treatment, wrapped in your soft bathrobe, take the time to extend the experience in the relaxation room, equipped with heated armchairs and bathed in soft music. An organic tea awaits you there, for absolute relaxation.
