There is a very accurate review, explaining that this is a rustic place, and ?I will not elaborate any further, as I agree with that person.
I would however add some tips. Taxi's from the airport, cost between 25-30 dollars, as it is not far from the airport, but it does take about 25-30 minutes, as the car needs to go around the airport to get to the house.
I made the reservation rather late, I booked it the night before my arrival, and no one was expecting us, although the booking went through and was accepted.
I was rather concerned, as I tried to reach the host on the phone given on the Air B&B website, but could not reach her. One of the neighbors noted we were there and guided us to the house of hte care taker.
The caretaker was more than friendly and she cleaned the place for us, cleaned the swimming pool, and helped us to get transport to the closest town, so we could get food.
The closest town is San Luis, which is closer to the airport than to the house, and it takes about 20 minutes on public transport, which is a pick up that goes picking up people on the main road. It was safe to us it, and food in San Luis was very good, and cheap.
The caretaker also helped us get transportation to the airport the next morning (Also a pick up), and she was there at 5 am waiting with the driver, to make sure we left as planned.
We everyone in that area extremely helpful and we appreciated that very much.
It is a clean place, good location, with no air-conditioner, but with fans which help keep the heat away and allows you to sleep. I believe as far as accommodation is concerned, you get what you pay for. Added to that friendliness and safety of the location is an added benefit of the place.
