TL;DR: Good location; outside noise creeps into unit; bad construction noise incidents from the apartment directly above the rental.
I'll try to be objective on this review so future renters will have an idea what they will be signing up for.
Good location. International Market mall is just around the block and Waikiki Beach is a 2-block walk. The unit looks like the pictures.
Outside noise could be bothersome to some people, if not most people. The noise of garbage trucks emptying dumpsters just outside the unit happens very early in the morning, often before 6AM. There is construction noise for most of the day on weekdays due to large building being built on the next lot - it won't finish until mid-2022. Expect lots of workers around the area and heavy equipment noise and traffic on the one way street leading to the apartment complex entrance. The windows are one-pane glass jalousies which hardly block outside noise.
Halfway during my stay, I experienced noise due to remodeling work on the apartment directly above ours. On four different incidents, I had noise so bad that I cannot even talk on the phone or to the person next to me. Tiles were being torn out using what sounded like a jackhammer trolley, sounds of power tools, loud banging, etc. The noise measured up to 90 dB (like having a lawnmower in the living room) making the unit truly unlivable. I reported this to the host every time. For the first three noise incidents I was refunded for 2 days. I requested that I be allowed to check-out early and that I be refunded for the unused portion of the reservation. The host and AirBnb rejected this request because "it was not the host's fault" so we had to stay in the unit. The construction work above our unit did not have a predictable schedule for us to make plans to not be in the unit while it was unlivable due to the noise. Expect this remodeling work to continue for the next few months.
On the fourth noise incident, I reached out to the host and AirBnb again. After a few days, AirBnb got back to me and initially rejected my request to check out of the unit early and get a refund for the unused portion of the reservation. The host did not respond to me regarding this fourth incident. Eventually, AirBnb granted our request to check out early.
