Shari's place was exactly what I was looking for during our Oahu trip. I stayed here with my girlfriend for a week. We wanted to stay away from the hustle of Honolulu (while still being only 25ish minutes to it). Overall the place was fairly cleaned and ready for our visit. The bathroom was nice and supplied (look under the sink before you purchase anything). The kitchen is well stocked and has everything you need to make breakfast or smaller meals (the hotplates seemed to work well-they won't turn on unless you have a plate on them). There a Whole Foods and other groceries nearby to purchase any items you may need. Although there was no washer/dryer, Shari's place was well supplied with towels, and with the drying racks outside, they worked out well.
Shari had a shower outside to wash off any sand before you enter, and right outside were several items for the beach including multiple boogie boards, an umbrella, a beach cart, coolers, and various other items. The only downside, as other reviewers noted, was that it is above a garage and is adjacent to the road, thus sound was sometimes apparent, but you could mostly ignore it (especially if you have lived in a city) and it was less during night. Noise really wasn't an issue for us. The parking was also an minor issue. The road is fairly busy, and I generally pulled into the larger parking space and then turned the car towards the street adjacent to the wall (basically parked as far as I could away from garage side, near a corner). When leaving, I waited until it was mostly clear and only pulled to the right (going to Kailua) as there are two walls which mostly block any view you have of cars coming on the opposite road. Once you tried it a couple of times it wasn't a problem either. Perhaps 5-7 minutes to Kailuatown and/or Kailua Park driving. Can also walk to the beach across the street if you like.
Overall I had a good time, and although I did not get a chance to meet Shari (I believe she was out of town), it was a very private place, easy to access with no issues, right in a nice area just outside of Kailua. Great if you want to avoid the tourist side of Honolulu hotels. Would stay again!
