Location is perfect - close enough to everything Waikiki has to offer: shops and restaurants right around the corner, 20 min to the beach. Location within building is also good- high floor with views, (i.e. you're not looking directly at another tall building), and partial view of the ocean from the balcony. Since you're not directly on the main streets, it's also quieter at night.
Our main problem was with the roaches in the kitchenette and bathroom. Roaches are not uncommon throughout the island, but we think these could have been avoided, had the cleaners done a better job - there were still food remnants and grease on plates used by previous guests that were stacked in the kitchenette area.
Wifi was a bit slow and kept dropping as well, but not problematic unless streaming and gaming is why you came to the island.
