Wow what an awesome find! Very different from the usual run-of-the-mill AirBnBs and not for guests who want pampering and all mod cons :)
This is an "off-the-grid" place which relies on solar power for electric, rain for water etc. Its has 6 double bedrooms and an outside shower (with tons of hot water) as well as an inside bathroom with bath. A kitchen and a TV room with stacks of DVDs. It has Wifi and uses the huge bottles of water for drinking/cooking.
The best thing about HawaiiAcres is its remoteness - in the middle of a working farm (Kelly and Matt run) with cows, 10 dogs (!), goats, chickens, pigs etc. The kids LOVED it!
We went with a family of 7 - 2 grandparents, 3 kids and 2 parents after spending 5 days on the west coast in the sun and beach at one of the Marriotts. We spent 6 days here and explored the larva flows, volcano, rain forest etc (note in December its the rainy season on the east coast which is very different to the west coast).
Matt/Kelly are on hand for anything and are amazing. They live on the farm close by, and are a fountain of knowledge of the island, conservation, where to go etc.
Matt gave the kids horse back rides on his horses too :)
I hope we can return soon!
