I had an 8-day reservation. After I couldn't sleep there the first night, I checked out and found another place.
The owner fairly refunded their airbnb rental income after I checked out and informed them of their house's unexpected mildew/mold smell, bad air, and poor cleanliness. The owner sounded distraught and was disappointed to learn about the conditions there and said they planned to deal with it right away. I suggested maybe they need a professional local manager and cleaner.
I was disappointed because of the hassle of finding another place and moving during precious vacation days.
It is otherwise a nice house in a nice garden/jungle setting with a wonderful porch. Nice fully equipped spacious modern kitchen. The tropical landscape, birds, and coqui frogs are charming.
If they can deal with the mildew/mold (and not just try to cover it up with chemical "air fresheners"), get a professional local manager, and cleaning, it would be a nice place to stay.
