In Song, a hotel needs to provide a certain number of upscale features to earn a 5-star rating. These can include gourmet restaurants, on-site gyms, saunas and spas, luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their outstanding standard of service. You can look forward to things like concierge services, nightly turn-down services and in-room massage. Some may even offer additional touches such as a welcome gift.
