Spa & Wellness

L’Institut Aspria by Sisley is an oasis of tranquility right in the heart of the city.

In 2014, Aspria Avenue Louise forged a partnership with luxury skincare brand Sisley to create a spa like no other – and the first Sisley spa in the country. Today, L’Institut offers unique blend of relaxation and beauty treatments for women and men, with expert facials, wraps and massage rituals using the brand’s luxurious skincare products, including Sisley’s famous skin-restoring phyto-aromatic face treatments.

Equally outstanding are our sauna, hamman and jacuzzi, perfect for relaxing and rejuvenating, whether soothing your muscles after a workout or just de-stressing from the world.

L’Institut is accessible to non-members.
