Donald's place was really great. It felt a lot more like you were living in Waikiki then it would if you were just half a mile east. We could easily walk to the main section in Waikiki beach within 15 minutes (tops) and there was an awesome lagoon even closer for us to take our kids to (4 year old, 2 year old, 1 year old).
We asked for a high chair and they quickly gave one to us. We also locked ourselves out of the apartment and they responded very quickly to help us out.
If you're looking to stay in the heart of Waikiki, it's not quite that, but it actually isn't as far as it looks on a map. You feel like you're in the heart of it all within 5 minutes of walking.
Parking was simple and free as well.
Would stay again for sure.
