Great location with parking included and is relatively clean. Good spot if you're just looking for a place to sleep at night.
However, given the location, the place is not very sound proof. Windows don't seem to keep much noise out. There is no ventilation in the bathroom either which WILL cause scents to travel through the place. There's also no place to sit inside the airbnb/place your luggage aside from one chair next to the toilet.
Overall, a good experience with some minor inconveniences that come with Airbnb's. The price being only slightly less than a hotel in waikiki, I would consider other options.
