In Max, a hotel needs to provide a specific amount of high-end amenities to be rated 5 stars. These can include on-site gyms, spas and saunas, gourmet restaurants, premium bedding, luxury bathroom products and more. What also sets 5-star hotels apart is their outstanding service. You'll enjoy things like concierge services, nightly turn-down services and in-room massage. Some may also offer extra touches such as welcome gifts.
