"Opened in 1885 on the very site where the hotel now stands, Les Bains Guerbois was the most famous private bathhouse in the capital and frequented by Parisian high society. Ensconced in the heart of today’s hotel, the spa is named after its predecessor and comes complete with a relaxation area, a lounge where you can discover the house’s range of fragrances, plus two treatment rooms tucked away in boudoirs flanking a large half-moon window." - Guide MICHELIN
