Le Royal Monceau Raffles, Paris

This historic property is just steps from Paris sights like the Arc de Triomphe and the Champs-Élysées, but would it be wrong to just stay in the bathroom instead? The Royal Monceau suite boasts custom Philippe Starck furniture, an acoustic guitar, and a curated selection of art, while its 320-square-foot salle de bain is a work of art in itself—all gleaming silver, an abundance of mirrors, and a healthy dose of natural light that keeps it bright and futuristic-feeling. Madonna, Robert De Niro, and Michael Jackson have all stayed here and taken advantage of the Clarins bath products (there's organic Bonpoint skin care for kids) and plush terry bathrobes.
