In Prim, a hotel needs to provide a specific amount of top-notch amenities to be designated 5 stars. These can include on-site gyms, saunas and spas, gourmet restaurants, luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their exceptional standard of service. You'll enjoy things like in-room massages, concierge services and nightly turn-down services. Some may also offer additional touches such as a welcome gift.
