On the plus side:
Great location super close to Volcano park, just a few minutes away
Quiet secluded location - feels like you have the forest all to
yourself
Pretty easy to find, even at night with Google maps
Having a good internet connection is nice for checking email and
uploading photos for facebook
Nice kitchen and lanai for cooking and eating outside.

On the not so good side:
Check in was not exactly smooth. When we arrived nobody was
at the house and we didn't know where the key was. Had to call
the host to find the location of the key (under the doormat).
When we opened the door to the room we were overwhelmed
with a stale musty smell - like the place had been closed up
and we were the first people to use the place in months...
The exterior is really in need of some freshening up, just starting
to look run down over time.

The interior has that 70's rustic cabin sort of look, not a big deal but be aware of what your expectations are. There was a dehumidifier in the lower level bedroom, so once we cranked that up and turned the fans on, the musty smell went away after a couple hours.
