In Namun, a hotel is required to offer a specific amount of upscale conveniences to earn 5 stars. These can include on-site gyms, spas and saunas, gourmet restaurants, premium bedding, luxury bathroom products and more. What also sets 5-star hotels apart is their exceptional service. You'll enjoy things like nightly turn-down services, concierge services and in-room massages. Some may even offer thoughtful touches such as a welcome gift.
