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