Although this place shows potential, I feel the owner stopped taking care. On arrival, the place was dusty, there were food leftovers in the kitchen, the bathroom wasn't properly cleaned and dusty. We found a flee in our bed. The pool was full of dead bugs. Note that the pictures on Airbnb seem to be several years old. Many things are worn out by now and needs replacement (cots, chairs, shutters). Some shutters are even rusty and sharp or even plain broken.
If the owner does a good refurbishing of the place, I'd say it's definitely worth the money. In its current shape, you will be screwed.
