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