Simon and Jeri's house is located in a rural neighborhood about 15 minutes from Hawaii Volcanoes National Park and half an hour from Hilo. The roads can be a little bumpy back to the house, but we were able to manage with a sedan although four-wheel drives are highly recommended for exploring the island. If you want to drive up Mauna Kea, you'll need a 4x4. We parked and hiked around the visitor center but didn't go further up the mountain. The house itself is absolutely charming and cozy and has everything you need plus more. Gotta say we loved having a/c after visiting Kailua-Kona! The real gem was being so close to Volcanoes Park. Once you pay the entry fee the tickets are good for a week. Do yourself a favor and go more than once. There is so much to explore at the park. The hiking, the lava tubes, the petroglyphs! It's all truly amazing. We would absolutely stay at Simon and Jeri's lovely house again!
