This was an excellent stay right in the middle of everything on the Kohala coast. For those new to the island, Hapuna beach in the title is one of the two best beaches on the island, and the other, Mauna Kea is right next to it. What is NOT mentioned is two of the best snorkeling locations (Kapa'a and Mahukona) up north are also about 15 minutes away. You are also in a great location to explore the north part of the island which has a lot to offer.
As for the house, two biggest highlights are the porch in the back, which is great for hanging out, and having a full kitchen, with absolutely everything you can imagine (and I mean everything.. you have access to a conventional oven, a mini oven, and a microwave, for example. Blender, coffee grinder, various condiments the host has made available for the guests.. the list goes on). Overall it was really comfortable with plenty of room. The little things made it better - we appreciated having several beach towels available, the Big Island guidebook in the living room, plentiful air conditioning for that one day we had to spend some time indoors midday, and being right on the road to Waimea as well. Debbie was extremely quick to respond to a couple of questions I had.
Negatives? Not really one but be aware the bed is on the firm side. If you like your mattresses soft and fluffy, it might be an issue. And if you are really set on Kona locations, keep in mind they will be ~30 to 50 minutes away.
