This is the 3rd AirBnB I stayed in during my time in Waikiki and was my least favorite of the three.
First, the good: Hiroki is an awesome communicator and is very helpful. He helped me move my things from one booking to another. He even let me have a late check out on the last day. The building itself is in a perfect location - literally in the heart of Waikiki, close to everything - especially the park and the beach. The building has good security features and I always felt safe. The apartment has the necessary amenities for an extended stay - coffee pot, fridge, stove, microwave, washer/dryer. It is easy to get to and easy to check in. The bed was comfortable and the linens were clean.
The not so good: This apartment is sort of meh and really needs some love. A fresh coat of paint and a deep cleaning would go a long way. However, this unit is located on the side of the building that is next to a very rowdy and loud hostel/short-term living complex. The windows are paper thin and you can hear everything. The AC unit is not great - it condenses on the floor and the breaker will trip if you use the AC and the microwave or hair dryer at the same time. Overall it is just a little bit jenky compared to the other units I stayed in. It's not BAD, it's just not GREAT - I would not choose this unit again if there are other options available.
