Cynthia was very responsive and her explanation clear.
The place is out of a fairy tale. Everything was as in the pictures. The oven is not working but the kitchen is really well appointed with plunger and coffee machine, pans...
The bed are heaven.
At night everything is pitch black and the sky is amazing for stargazing.

What we did from the Log Cabin:
We landed in Hilo, shopped at Island Naturals then headed to the Log Cabin.
My husband went running the Kilauea Iki Trail in the morning as it is only 5 min drive away and we spent 2 days exploring the NP.
Day 1 - Volcano NP, Kilauea Iki Trail is great with kids, easy if you do it really early in morning or after 3pm. Byron ledge was our second favorite. Between 10am and 2:30pm at least it is way to hot to walk.
Crater chain road is nice and the view is spectacular.
Go to the Jagger Musuem at night after diner was another great treat to see the lava reflect it s glow on the smoke.
Day 2 - Drove to Kalapana, walk to the beach then headed to the Kapoho tide pools, road is beautiful. Lava tree area was close as the tide pools so enquire before.
Day 3 - We drove to Kealakekua Bay for a lunch on the grass starting by an early stop at Black sand beach where we spent time watching the turtle and then went to Green sand beach. We didn't walk or either paid to go to green sand beach just went down to the beach on the right side after the parking and found some olivine sand. Then we went to the amazing jump spot on the cliff at the southern point it was awesome. The return from Kealakekua Bay around 4pm was gorgeous with the light.
All of this better with early start.
We could have honestly stay for longer.
