In Karvio, a hotel must provide a specific number of top-notch amenities to be rated 5 stars. These may include gourmet restaurants, saunas and spas, on-site gyms, luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their guest-focused standard of service. You can expect things like nightly turn-down services, concierge services and in-room massages. Some may even offer additional touches such as a welcome gift.
