In Sigapon, a hotel must offer a certain level of high-end conveniences to be designated 5 stars. These may include on-site gyms, saunas and spas, gourmet restaurants, 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 extra touches like a welcome gift.
