Shelly and Nick provide a few rooms (with ensuite showers) for guests which are comfortable and well looked after. The common room is a nice relaxing place with tv (if you can't get away from that on your holiday). There is a covered area with cooking facilities (inc bbq) if you want to stay in and not go out to eat.
I enjoyed my very relaxing stay there with the cats, wild horses and iguanas occasionally wandering around and the peacock nearby.
It's a 25 min walk into the nearest town (Isabel) but it's easy to hitch or you can start to walk and get offered a life by locals or anyone else. Vieques is a friendly place.
