It's a great place. It's fairly centrally located, walking distance to Ala-Moana with fabulous views, it's on the 12th floor. It's a bit of a hike to the main drag of Waikiki, but buses run frequently past the door, or it's a $10 taxi ride.
The lifts during the christmas season were packed, sometimes having to wait for a second or third one.
It's interior is also top notch, although the beds were very firm and the sofa bed very uncomfortable, I wouldn't recommend it for an adult.
The only disappointment is their policy on food, you bring your own and emtpy it out at the end. So you're starting with nothing, a stark contrast to any other AirBnb's we've every stayed at (admittedly not many).
Oh, and we were disappointed with Goofy's cafe a couple of doors down, not much kid friendly food there. If you're exhausted I'd go with the Subway or the McDonalds just across the street instead.
