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