What a fantastic place! So clean, friendly and serene. Also very responsive, responsible hosts. Definitely off the beaten path but was a good location for exploring the east Side of Hawaii and especially Volcano National Park. We stayed here for the first three nights of our honeymoon and enjoyed this stay very much. It was also our very first time using VRBO. There were a lot of extra nice pluses to our stay, including the ionized water, option to use the kitchen, and the host's kindness to meet us after check-in hours although we came in on a late flight. Another thing we liked was meeting some of the other international guests during the casual (but tasty & healthy) breakfast. The road to the place requires you to drive slowly so be sure to allow about 15 minutes of 5-10 mph. 4WD not necessary but in Hawaii there are many rocky roads so take it slow. High accolades for Celestial Sanctum and we would love to stay there again.
