The Oasis Guest House has 2 rooms available when I was there (May 2015). Both rooms are decorated nicely and have kitchenette's which is great for keeping snacks and cold water available. at that time only one room had air conditioning, which is wonderful at night!
As you can see in one of my pictures, there is a third floor with a palapa where you can have 360 degree views of the village and the Caribbean Sea, as well as a cooling trade wind breeze.
Christine, the owner is very gracious and helpful if you need anything.
