In Trevijano, a hotel must provide a certain amount of upscale amenities to be designated 5 stars. These may include gourmet restaurants, on-site gyms, saunas and spas, premium bedding, luxury toiletries and more. What also sets 5-star hotels apart is their guest-centric standard of service. You'll enjoy things like nightly turn-down services, concierge services and in-room massages. Some may also offer thoughtful touches such as welcome gifts.
