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