Name aside, you will not likely see monkeys on the property; there's a local tour to meet a family of monkeys but the pond the house is on doesn't have them. We did see iguanas, lots of birds, and even an errant crocodile that the host said they are working to relocate.
The house is clean and functional. The downstairs is a kinda weird space, like a basement almost, and you just pass through it to get to the stairs. You can't use the toilet or washing machine down there. Upstairs is comfortable--no TV, so have a book for the covered porch hammocks. The porch furniture is pretty worn, but functional. The kitchen had every tool we needed.
The location is very remote. There are zero restaurants and stores, so either get a car (good luck navigating!) Or make sure to have everything you might need, as others have said. We heard children singing at the Mennonite school down the street in the morning and there were roosters and sheep across the street.
Relaxing and isolated vacation spot.
