Nice location with a great view, AC, free parking, walkable to Waikiki. Building is a little old but nothing to complain about. Laundry is on site (machines take credit cards - no change, yay) and there is security in the building. There was a little construction while we were there so we had a long wait for the elevator a couple times, but this doesn't seem to be the norm.
Caroline is a wonderful host and any questions we had were met with super-fast responses. She has included many thoughtful touches throughout the room to make the stay more enjoyable.
