In Lingoni, a hotel must provide a specific level of high-end conveniences to earn a 5-star rating. These can include gourmet restaurants, saunas and spas, on-site gyms, premium bedding, luxury toiletries and more. What also sets 5-star hotels apart is their superior service. You'll enjoy things like nightly turn-down services, concierge services and in-room massages. Some may also offer special touches like welcome gifts.
