Staying at Nanette's place is INCREDIBLE. Truly. Nanette herself is so kind and communicative, everything was as described - well, actually - in some cases we were taken aback by how things were even better than we expected. There are wonderful outdoor spaces to relax and eat (and you'll likely be visited by curious geckos!), the inside is extremely comfortable. Perfect for a couple, a group of three, or two couples/four (there are two beds and two bathrooms and a great little kitchen with all you might need to make your own meals if you prefer to grocery shop rather than eat out all the time!). It was our first time to Hawaii, and we weren't sure if we wanted to be staying outside of Kona and Captain Cook, but as we learned the place is a perfect distance out of the more tourist-heavy areas while still being an easy drive to any of it you could want, and there are some awesome places to eat or snorkel just up/down the road to Kona Paradise. Pebble beach down below the house is a great spot for more snorkeling or to sit on the pebble rocks, and we made a habit of watching the sunset each night from either the beach or the balcony. Seriously, this is such a little gem. My wife and I had to cut our trip short due to a pet emergency back home and my father-in-law stayed behind, Nanette was checking in on us and was so caring! She made sure my father-in-law was all set without us. She also texted us updates on some island closures due to a very uncommon large brush fire up north just in case we were headed that way - what a thoughtful person!
If you're wondering about if this is the spot - I'd say just go for it. All the amenities you'll need to be comfortable in a great great very private location where you'll feel totally prepped and cared for by the host's considerations. As others have noted - it's a bit steep driving in and out, including the driveway - so be careful with any cars that have very low clearance. But everything is paved, so I imagine in most cars you'll be totally good to go.
