Rick's place was great! We had four people stay in the room and found that we had enough space for everyone. The parking spot was a huge bonus as it is very difficult to find parking in Waikiki.
Like others mentioned, it can get pretty loud towards the night due to a nearby club, but the noise dies down after 10 PM.
The AC unit is pretty loud. However, I am a light sleeper and did not wake up from the noise.
There is a washer/dryer on the floor which is nice. One load of laundry cost $3.
A few points of improvement: have more bath towels in the room (we were given 2 normal towels and two beach towels. Rick was able to provide more upon request). Also, have extra toilet paper (there are two rolls provided in the bathroom).
Overall, I liked the place and would stay there again!
