Great place! The name is Jungle "Hut" but it is anything but a "hut"! I could easily have stayed and lived out my days here! The "hut" has a full kitchen, spacious living room, single bedroom (but also a futon in the space between the living room and kitchen), and sizable bathroom. And to fall asleep in the jungle to the cuqui frogs' singing is like falling asleep to nature's lullaby! I cannot wait to stay here again!
(FYI...a bit of a challenge to find in the dark, so try to arrive in daylight, keeping in mind sunset hits early in Hilo. If you are arriving after dark, the left turn onto Maku'u is exactly as Liz says - 1.0 miles after Paradise Drive. If you've gone 1.3 miles, you've gone too far. I say this because at the time I was there - October 2012 - the street sign warning of Maku'u, when coming from Hilo, was bent and really scuffed up so much as to be illegible.)
