In Puerto Rico, a hotel must offer a certain amount of high-end amenities to earn 5 stars. These can include gourmet restaurants, on-site gyms, saunas and spas, premium bedding, luxury bathroom products and more. What also sets 5-star hotels apart is their superior standard of service. You can expect things like nightly turn-down services, concierge services and in-room massages. Some may even offer extra touches like welcome gifts.
