In Tonu, a hotel must offer a certain level of upscale amenities to earn 5 stars. These may include on-site gyms, spas and saunas, gourmet restaurants, premium bedding, luxury toiletries and more. What also sets 5-star hotels apart is their guest-focused service. You can look forward to things like nightly turn-down services, in-room massages and concierge services. Some may also offer additional touches like a welcome gift.
