We stayed four nights during the last leg of our two week trek around the big island. We loved the waterfall, feeding the animals, and playing with the two boys. The unit was clean and had everything we needed for cooking, cleaning, and sleeping. Curtains over the windows would make a big difference for those early morning sunrises or for taking an afternoon nap since the blinds let a lot of light through.
Expect plenty of farm noises like the morning turkey gobble and LOTS of noise from the host family upstairs. It was consistently quiet from about 11pm to 6am.
