We had the pleasure of staying with Clarita and Orlando in early December, 2012.
Food was great, interesting selection of other tourists, 24/7 service. very clean, etc.
But what really set them apart was their ability to connect us with Cuba. Lots of great conversations about what to do and why, but they also arranged for us to spend a day with a fellow who teaches at one of the local Colleges. He showed us the Havana of Cubans. He explained current politics, how things got to be the way they are, how most Cubans survive, etc. They he took us to a great restaurant which is really just for locals.
We were interested in a few days at the beach and they made reservations with another casa in Playa Larga.
Good cheer, good times. (great location).
What more can I say?
