In Amargos, a hotel needs to offer a specific number of high-end amenities to earn a 5-star rating. These can include saunas and spas, on-site gyms, 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 in-room massages, concierge services and nightly turn-down services. Some may even offer extra touches like welcome gifts.
