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