My husband and I stayed at Kaia's guest house for one week, the most comfortable Airbnb stay we've ever had! The guest room is located at the bottom of the house (the family lives upstairs) but has a private entry that faces the west. The house is located in a very nice neighborhood at higher elevation and has a magnificent view of the ocean and part of the city below. So, you can watch the sun set over the ocean every night! The house is spacious for a couple, maybe a little tight if you have more than two people, but it will accommodate up to four. The house is well-equipped, with a full kitchen (gas range, full fridge/freezer, coffee maker, toaster, etc.), a spacious bathroom, and even an washer and dryer. It also has several towels, including beach towels, some boogie boards, beach umbrellas, beach chairs and mats, and a cooler with ice packs. I have never seen a guest home so well-equipped!
While the house is away from the "action" of the town, it offers such a serene and beautiful view. It sits on the side of a mountain near some Kona coffee plantations, and as such, enjoys cooler weather (around 10 degrees cooler than the coast). We preferred the quiet, but you will definitely need a rental car. At night, coqui frogs will serenade you, and while they are loud, their sounds are beautiful and never kept me awake, even with the windows open.
Nearby is a Japanese supermarket where you can get bento box meals and other sundries. There is also a Safeway, a Target, and a Walmart (and even a Costco!) just a few minutes away by car.
I would recommend this stay to anyone wanting some peace and quiet. It is truly a remarkable home with such gorgeous views, and you'll never regret staying here.
