This is a very conveniently located condo in downtown Waikiki! We loved how close it was to the beach and the zoo, and having access to parking is a huge plus in this city. The rental staff were easy to reach and communicate with, and we didn't have any major problems while staying here. The floor was a bit dirty when we came in, but otherwise it was clean and ready for us when we arrived.
There are probably no really quiet places in this area, but it is still the case that this was a particularly noisy location, even for Waikiki. The window and balcony face a very loud and busy hostel (which means the view and atmosphere are not so nice, so we also didn't use the balcony at all). I stayed here over a week to attend a conference and get some work done, and I was ultimately not able to very peacefully work in the condo because of screaming people, barking dogs, etc. I had to run the a/c or fans at night to drown out the noise.
The laundry is building-wide and not free, but it works fine and isn't very expensive. It is basic, coin-operated laundry, but there is apparently also now a phone app for it (which I only discovered after spending days scrounging for quarters!). I didn't experience a wait for the laundry machines, so it was not terribly inconvenient.
The kitchen is nice and has the essentials. Unfortunately, Waikiki actually really lacks grocery stores, so if you are hoping to use the kitchen for meals your options are either to get out to another part of Honolulu for a proper store, or to mainly work with convenience store food. This is fine (and is a Waikiki problem, not an issue with this condo), but it might help others to know in advance. Restaurants in the immediate area are also all crowded and expensive, but there is a line of more affordable food trucks half a block away. I did not discover this for days, but it was a nice alternative once I did.
