In Shangkeng, a hotel needs to offer a specific amount of high-end conveniences to be designated 5 stars. These can 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-focused standard of service. You can expect things like nightly turn-down services, concierge services and in-room massages. Some may even offer thoughtful touches like a welcome gift.
