In Deer, a hotel must provide a certain level of upscale features to earn 5 stars. These can include on-site gyms, saunas and spas, gourmet restaurants, premium bedding, luxury bathroom products and more. What also sets 5-star hotels apart is their extraordinary service. You can look forward to things like in-room massages, nightly turn-down services and concierge services. Some may also offer additional touches such as welcome gifts.
