Awesome place. We stayed here for 2.5 weeks and enjoyed every minute of it. It is a beautiful house in the jungle, far from everything but close enough if you need anything. Nice area to walk around. Mermaids ponds were our favorite walkable thing. Hilo was close (less than 1 hour) and we absolutely loved the market and beaches (richardson mainly) there.
The view from the roof of the house is spectacular, a great place to star gaze at night. I also loved the hammock on the second floor. I suggest bringing ear plugs because you are in the jungle and the frogs can get a bit noisy for light sleepers.
Robert and his wife were very accommodating showing us all the local places to go. They even picked exotic tropical fruit from their tree for us. The papaya and the Rambutans were delicious.
The internet was fine, fast enough to do anything you could want, zoom was good, sometimes small delays at times but we didn't seem to notice too much. They have two internet options so when the first option is down (usually due to a recent storm) they have satellite system that always worked.
The road (gov beach road) on the way to Robert's is one of the most beautiful roads you will drive on with a tree canopy above you and the ocean cliffs on the side.
This is an amazing little house in the jungle and I highly recommend it!
