Chris' place is in the most convenient location in Waikiki. It is tucked in 2 blocks from the busy street and is near many delicious restaurants within a few minutes walking distance. Overall, we enjoyed our stay and I will details the pros and cons below:
Pros: convenient location, excellent communication (responded very quickly), safe building (building access regulated after 9PM), relatively affordable stay compared to other lodging options.
Cons: Cleanliness is something to be desired -- it isn't dirty, but we could tell that the building/room was old and could use minor upgrades (replace toilet, shower tub/head, paint job etc); also I could find hair and other dirt/crust on the bedsheet on the pull out sofa, Noise - the window in the room is made of glass blinds; the noise from the street below permeates VERY easily and kept us up for a while until the traffic died down, AC - also extremely loud and could be replaced with a more efficient window unit.
Overall, since we really only used the room to sleep after returning from our trips at night, the cons mentioned above affected us only a little bit. Value-wise, it is a no brainer if you can overlook some deficiencies above. I stayed at the Hilton across the street for a week and the daily room + resort fees were almost triple the amount from that of Chris'.
