In Central, a hotel needs to offer a specific number of high-end conveniences to be designated 5 stars. These can 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-centric standard of service. You can expect things like concierge services, nightly turn-down services and in-room massage. Some may also offer additional touches like a welcome gift.
