In Obe, a hotel needs to offer a certain number of high-end amenities to earn 5 stars. These can include on-site gyms, gourmet restaurants, saunas and spas, complimentary luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their guest-focused service. You'll enjoy things like concierge services, nightly turn-down services and in-room massage. Some may also offer thoughtful touches such as welcome gifts.
