Overall we enjoyed our stay. The main living space is clean and nice. The shower has some mold/stains on the grout and on the tub, but it did seem clean/sanitized. The balcony was nice, you have a partial view of the mountains and a city view.
The bed is quite uncomfortable, it has zero support so I was left with a sitff neck each morning.
The AC unit works well to cool the unit, but is extremely loud. This part of Waikiki is very busy and thus quite noisy, but we didnt mind because it was incredibly convenient. There are several food and convenience stores within 1 block, including two restaurants in the lobby of the building.
They do have quite an early checkout time (10am), and this left us in a sticky situation because our flight was not until the evening. We contacted the host and they basically told us we were SOL and had no suggestions. That wasnt great... but we asked the manager of the building and they accommodated us.
