Château des Fleurs 

The place

Château des Fleurs stands beside the Arc de Triomphe, in a 1910 building at the top of the Champs-Élysées. Barcelona studio Quintana Partners looked to Art Nouveau and the Belle Époque — elegant, a little playful.

The 37 rooms and suites are light-filled and muted: vintage-inspired furniture, dark wooden floors, deep velvet, large Parisian shutters. Bathrooms gleam with polished fixtures and red and white ceramic tile.

Below, Spa by Omnisens keeps a plunge pool in red checkered tile, a sauna, treatment rooms, and a fitness center. The bar and lounge hold the ground floor. No restaurant here — Paris takes care of that, just outside.
