We could see the red glow from the volcano from outside the house on some nights! You are a 5 minute drive to the Volcanos National Park which is open all night for viewing. We stayed in the mountain for 4 nights during our month long Hawaii getaway to experience something outside of beaches. The owners are extremely responsive in resolving any issues. I arrived in the evening and was concerned the wifi was slow for work, they had someone out the next day to resolve it. The A Frame cabins are on a private dirt road along the golf course and they will send you simple instructions on how to find them. There are 2 A frame cabins next to each other with a huge shared deck. We barely noticed there were people in the other building because the are angled away from each other. You will have absolutely everything you need, including bath products and laundry detergent. Just stop by the store for snacks and food.
Due to Covid, there are not a lot of restaurants open. The Kilauea Lodge & Restaurant was fantastic and about 8 minutes away, but make sure you make a reservation a couple days in advance due to limited seating. The drinks and food were delicious. They also have an awesome little gift shop with great prices on items from Hawaiian artists. The town of Volcano does not have a supermarket, the closest supermarket is Foodland Kea`au, about 25 minutes towards Hilo. I would recommend planning ahead so you don't have to backtrack.
