Good stay overall -- I appreciated that there was reserved garage parking available in the building (for an extra daily fee) if you're renting a car. Great views from the two balconies (one looking north toward the mountains, and one westward overlooking Waikiki with partial ocean views). AC wall units in each of the three main rooms; clean throughout.
The master bedroom's bathroom shower/tub could use an update (the knob to switch the water from tub to showerhead is hard to pull), and in general there could be more/better lighting, as well as some power outlets or a power strip near the beds in the master bedroom.
NOTE RE: LOCATION: At least for me, the address shown in the Airbnb listing (once my booking was confirmed) was *different* from the actual condo building address sent to me later by Royal Waikiki via an email closer to the trip date. So make sure to confirm the address with Royal Waikiki before you start making itinerary plans based on the initial address stated by Airbnb in their booking confirmation.
