These may include saunas and spas, on-site gyms, gourmet restaurants, luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their outstanding standard of service. You'll enjoy things like nightly turn-down services, in-room massages and concierge services. Some may even offer thoughtful touches such as a welcome gift.
