An art-deco landmark built in 1928, this Palace Hotel is nestled in the Golden Triangle of Paris, just off the historic Champs-Elysees. Classy rooms recreate the atmosphere of a luxurious Parisian apartment, and the three restaurants has five Michelin stars among them. Facilities include a decadent new spa and an elegant indoor swimming pool. (Renovated: 2015; Rooms: 244)
