This place was fantastic for my family of 4. Our kids were able to stay on the pull-out or extra room bed. The main bed was comfortable. Kitchen had all the basic needs and there was a full sized fridge. House was easy to get into and super clean when we arrived. The unit shares a wall with an adjacent one, but that never seemed to be an issue for us noise-wise (there was another guest staying at the adjacent side).
I'd highly recommend this and to anyone else looking for an affordable, extended stay near Kona.
