Although there was one negative review, I elected to disregard it, because it related to a scheduling problem and not the experience of actually staying in a casa. How delighted I am with my decision.
My recent stay - march 10 -12 was truly a unique experience and far exceeded my expectations. What led me to this conclusion and what can I say about Casa Lucio y Nirma? A great deal and all of it good.
The casa itself, within easy walking distance to downtown Vinales, was immaculate as was my room, which while a part of the house is separate affording the visitor much privacy. More especially the bath was clean. They both smelled fresh.
The owners - Lucio and Nirma - live at the casa with their two children, both college graduates. All four were welcoming and helpful without being overly attentive. A good example- when they realized that I didn't like to do the usual tourist things, they made a real effort to find things off the usual tourist paths. This led to a trip to a dental clinic (the daughter is a dentist) and a trip to a pineapple farm in an area at the end of the electric grid.
If you want to see how real Cubans live and you want to experience warm Cuban hospitality, I recommend this casa without reservations.
