We stayed at this apartment for a one week trip to Oahu. The free parking garage access was a huge selling point, and it was very easy to get in and out multiple times each day (unlike valet parking at nearby hotels). It is a 5-10 minute drive from the east side of Waikiki to the main highways, but this location is no worse than any other downtown spot for driving.
Overall, this was a great place to stay! It is on a high floor in the building with great mountain views to the north. It is a one bedroom (instead of a studio like many others in the area) for a bit more room. The kitchen and bathroom renovations are gorgeous and fairly new. We set the AC to run the fan all night (which I would recommend to keep air circulating), which was fairly loud but helped cover up any hallway sounds.
I would highly recommend staying here if you want a good location to drive to other parts of the island while still being walking distance to Waikiki and the beach.
