In Tiga, a hotel must offer a certain number of upscale conveniences to earn a 5-star rating. These can include gourmet restaurants, saunas and spas, on-site gyms, luxury bathroom products, premium bedding and more. What also sets 5-star hotels apart is their guest-centric standard of service. You can expect things like concierge services, nightly turn-down services and in-room massage. Some may even offer additional touches like welcome gifts.
