Overall, we enjoyed our month at Jeff's place. It was a good choice and we recommend that you consider it too!
Pros - location (a few blocks from the quieter end of Waikiki beach and close to bus stops), Jeff's communication (provided clear instructions for check-in and check-out), the property manager (Carlton clearly takes pride in keeping the property nice and wants you to enjoy your stay), and certain amenities (nice bathroom, solid internet connection, easy-to-use shared laundry facilities, and comfortable air conditioning & fan).
Cons - other amenities (a broken dining chair, microwave doesn't spin, broken lid for coffee maker, soft bed, and an older assortment of kitchen dishes/pots and pans/knives), the wrong wifi name and password in the house manual (we eventually found the router and connected), and little natural light (due to frosted windows, but they can be opened). We didn't complain to Jeff because they weren't big problems; just reasons for our 4 star review.
