In Nutrioso, a hotel must provide a specific number of upscale conveniences to be rated 5 stars. These may include gourmet restaurants, saunas and spas, on-site gyms, complimentary luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their guest-focused standard of service. You can look forward to things like in-room massages, concierge services and nightly turn-down services. Some may also offer additional touches such as welcome gifts.
