We enjoyed our short stay at Criss' unique place. Kehena beach was a huge highlight for us and we loved being so close. It was more of a "glamping" experience but also clean, neat, and comfortable. Three little huts on her property have 1) the large studio bedroom 2) small kitchen with electric cooler "fridge" and 3) outhouse with toilet (cannot flush toilet paper) and outdoor shower. Coming from a colder climate, it felt pretty hot in the bedroom even at night with all the windows open. I'm not sure if the solar power is strong enough to run a fan.
Compared to other islands the price is great, and Criss was very responsive and helpful! I would just note that the kitchen is quite small and the sink has non-potable water, but there is a 5 gallon jug of drinking water there too. The outdoorsy feel is very appropriate to the atmosphere!
