In Sam Kha, a hotel must offer a specific level of top-notch amenities to be rated 5 stars. These can include gourmet restaurants, on-site gyms, saunas and spas, 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 concierge services, nightly turn-down services and in-room massage. Some may even offer thoughtful touches such as welcome gifts.
