Hong's apartment is really a good choice. Great view, comfortable bed, kitchenette well equipped, and only 10 minutes by foot to a wonderful beach (Duke Paoa Kahanamoku Beach Park). Equally important for me is the short distance to the Hawaii Convention Center (only 6 minutes by foot). Waikiki is, of course, busy and loud, so I slept with earplugs.
Overall, it was a great time there.
