In Alpha, a hotel needs to offer a specific number of upscale amenities to be designated 5 stars. These may include on-site gyms, saunas and spas, gourmet restaurants, complimentary luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their outstanding standard of service. You'll enjoy things like in-room massages, concierge services and nightly turn-down services. Some may even offer extra touches such as welcome gifts.
