My girlfriend and I stayed at Chad's place for about a week. Chad and Jennifer are awesome hosts: very fast communication, super friendly people, gave great tips on what to do/see on the island etc
Their property is absolutely gorgeous (which Chad gave us a tour of on our first day) - easily the best Airbnb I've stayed at. It includes several acres of land, beautiful views of the ocean, an awesome hot tub and pool deck, a horse riding arena, and Opihi point which is a sacred point on their property that also provides spectacular 270 degree view of the ocean.
I'd highly recommend anyone to stay at Chad's place. I know I'll definitely be staying here again when I come back to Big Island in the future.
