The place is good for the price that it has. The gravel road is just for around 2 miles and we rented a medium size car which worked perfectly in that road. A compact car could also do it, you just have
to go a little bit slow. The place is a little far from Hilo so you cannot expect to go in/out several times during the day because you would loose to much time driving. On the other hand everything in Hilo closes at 6 pm so there's not much to do at nigth either. The place was clean enougth and gets the job done, to sleep at nigth.
