Flawless guest service is the defining feature of every 5-star hotel in Cuba. From the minute you step through the door, staff cater to your every whim, whether offering luggage assistance and storage or providing a turn-down service. What's more, hotels must offer upscale amenities to be eligible for a 5-star rating. These can include luxury toiletries, on-site spa facilities, pools, fine dining kitchens and knowledgeable concierge.
