We are originally from Honolulu, and we stayed at Hua's condo for 12 days while on the islands visiting family. The building is new, maybe a year or two old. The location is fantastic! It is on Kapiolani Blvd, near the Ala Moana shopping center, the Ala Moana park and beach, and tons of shopping and nightlife all within easy walking distance. Given the traffic nightmare in Honolulu, this is a huge plus. If you do have a car (and we recommend you get one), the condo comes with an assigned parking stall, which is a huge plus since most hotels in the area charge $30 or more per night for parking. We felt completely at home after a couple of days.
The stay had very little downsides. One was that apparently the place has a full time resident, and when we checked in, though the condo was "picked up" it was not professionally cleaned. Once we let Hua know about the condition, she immediately addressed the issue even though she was vacationing in China. She got in touch with one of her friends who arranged the very thorough cleaning within a day. Hua was very apologetic of the issue and gave us a credit for a day's stay for our inconvenience. As a full time residence you will find personal items around the condo (this arrangement seems to be about 50/50 in my limited Airbnb experience) but for a week or so stay you get used to it.
In all, this condo is one of the best options in Honolulu and I would certainly keep this in mind next time I come back to the islands.
