The new Cheval Blanc Paris is a luxury hotel created specifically for the lifestyle of the 21st century. The 72-room property opened last September and is owned by the world’s largest luxury goods conglomerate, LVMH. (Cheval Blanc also has resorts in Courchevel in the French Alps, St. Tropez, St. Barths and the Maldives.) The Paris hotel occupies an art deco structure, designed in 1926 by pioneering architect Henri Sauvage, which is the most distinctive of four Seine-side buildings that formerly contained La Samaritaine department store, once the Macy’s of Paris.
