In Tufi, a hotel is required to offer a certain amount of upscale features to be designated 5 stars. These can include gourmet restaurants, on-site gyms, saunas and spas, luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their outstanding service. You can expect things like in-room massages, nightly turn-down services and concierge services. Some may even offer extra touches such as a welcome gift.
