Kimpton St-Honoré

The building alone stops traffic: a 1917 Art Nouveau fixture near the Palais Garnier, with turquoise, copper, and gold detailing just ornate enough to upstage its neighbors. Inside, designer Charles Zana layered Déco and modernist touches over the original bones, landing somewhere stylish without tipping into austere. Rooms run gem-toned and generous by Parisian standards. A Codage spa and mosaic-tiled pool push it into luxury-boutique range, and the restaurant goes Californian, because Paris has enough French food.
