First off. Best AirBnb I've been to. We've been traveling and have tried several other "super host", and Sandra's place was the best super host thus far.
It was called Sandra's Retreat, and it really lived up to the name. Very private, spacious, and lounging around the outside was great. It was sort of like a patio/porch mixed with outdoor man cave. Whatever you want to call it, the outside area reminded me of a place to have a lazy afternoon or early morning cookout in your pajamas without fear of neighbors. The interior had well positioned bed, kitchen, and bath. Snorkel gear, flashlight, beach towels, grilling utensils, and outdoor shower were included.
The only downfall was minor and not really an issue with Sandra's, but the Big Island itself. This was the driving involved. No matter where you stay in the Big Island, expect to drive to do anything. It's an easy 20-40 min drive to most activity areas.
