My stay at Greg's place was very pleasant. Even before I arrived, he was very responsive to all my questions. I also appreciated how he gave very clear directions on how to find and enter the house. Greg and his girlfriend were very friendly and welcoming, as was their cat.
Also, the location was perfect for me. Their place is located in a quiet residential area. It took about 30 min. to walk to the heart of Waikiki. It is also walking distance (10-15 min.) to restaurants and shops on Kapahulu Ave. There is a Biki station within a 10 min. walk if biking is preferred.
