We had 10 people and this place had tons of space. Very well appointed kitchen. We cooked several times and the only thing we couldn't find was a pizza cutter.
Probably the most comfortable bed I've ever slept in in a rental. Three full baths two of which have double sinks separate from the toilet and shower was nice for a large group.
Nice quiet area close to the national park. We did find out that if you try to go out for dinner in Volcano with a large group to call ahead for a reservation.
Made good use of the provided cooler and ice blocks when out day-tripping.
The bedrooms and bathrooms were a bit dimly lit and the house was humid enough our towels didn't dry (there's no A/C or vent fans in the bathrooms and it rained every day we were there).
The driveway was a bit difficult to find and to navigate especially at night. When you pull in, you go up and over a rather substantial hump while turning to avoid a wall. By the end we were better at it at found it better to back in and drive out rather than drive in and back out.
