Jim and Jenny were absolutely phenomenal!! My wife and I stayed at their guest house for a big chunk of our honeymoon. It was perfectly situated for us - secluded enough that we could come home in the evening and listen to the sounds of nature while we watched the sunset from the porch, and still not too far from activities around Kona or Volcano National Park. For us, the off-grid property was a plus - we appreciated being able to reduce the environmental impact of our vacation by staying in a green home. For those apprehensive about this sort of set-up, don't be dissuaded - there was more than enough water and electricity for us, and the space is abundantly comfortable. It was barely distinguishable from a grid-connected home.
Breakfasts were generous and delicious, great to kick off our full days on the island. Jim and Jenny had great local knowledge and were able to provide some stellar recommendations with regard to sites and activities. In additional, they are both very kind, responsive, and accommodating.
We strongly recommend!!
