The view from this apartment is stunning! If you are exhausted from your day on the island and can't make it down to the marina for sunset (right across the street and the best spot to watch the sunset in Waikiki), you will still have a fantastic view. The AC provides some white noise and thus I never heard any noisy neighbors if there were any. Everything is very clean and tidy and there are plenty of cooking supplies. Having secure parking is also a huge plus.
The only drawback was the sometimes-out-of-order elevator/s. I had great luck my whole trip, until the last 12 hours when both went out for a little while and I had to climb the 31 flights the night before I left and hope that they were up and running in a few hours when I would leave for the airport and need to make multiple trips to my car for luggage and taking out the trash, etc. Thankfully, one of them was working by the time I had to leave so it all worked out, but be aware that if you get unlucky you could get into a tight spot. Aside from that, this was the perfect spot to rest and recharge on my trip!
One tip: the address isn't easy to find from the street and google maps isn't very helpful. The building is tucked back between two other tall buildings, and the number isn't displayed. Look for a sign with a blue logo that says Waikiki Marina.
