In Leines, a hotel needs to offer a certain number of high-end conveniences to be designated 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 outstanding standard of service. You can expect things like concierge services, nightly turn-down services and in-room massage. Some may even offer extra touches like welcome gifts.
