In Toso, a hotel must provide a certain number of high-end conveniences to earn a 5-star rating. These may include on-site gyms, saunas and spas, gourmet restaurants, premium bedding, luxury toiletries and more. What also sets 5-star hotels apart is their superior standard of service. You can expect things like nightly turn-down services, in-room massages and concierge services. Some may even offer additional touches such as a welcome gift.
