In Romance, a hotel must offer a certain level of high-end conveniences to be designated 5 stars. These can include on-site gyms, gourmet restaurants, saunas and spas, premium bedding, luxury bathroom products and more. What also sets 5-star hotels apart is their superior service. You can expect things like nightly turn-down services, in-room massages and concierge services. Some may even offer special touches such as a welcome gift.
