In Havana, a hotel needs to provide a certain number of upscale conveniences to earn a 5-star rating. These may 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 guest-focused standard of service. You'll enjoy things like nightly turn-down services, concierge services and in-room massages. Some may even offer special touches such as welcome gifts.
