In Nash, a hotel must offer a specific level of high-end amenities to earn 5 stars. These may include gourmet restaurants, saunas and spas, on-site gyms, premium bedding, luxury toiletries and more. What also sets 5-star hotels apart is their guest-centric service. You can expect things like nightly turn-down services, concierge services and in-room massages. Some may even offer thoughtful touches such as a welcome gift.
