At Spa Mosaic at the Hilton Arc de Triomphe, a maze of Art Deco tiles dot the floors surrounding a giant hydro-tonic bath while resting in a surprisingly residential environment. But the reserve stops there. Treatments run to the more exotic, particularly when delivered in the spacious Hammam. The hand-tiled, fairy-tale-like chamber makes you feel like you could easily be in Istanbul rather than in Paris. The unmistakable savoir fare, however, lets you know exactly where you are.
