First, about the place: The location is amazing. It was hard to fall asleep when I got home without the soothing sound of the ocean waves lulling me to sleep. We really enjoyed sitting on the lanai with a glass of wine at the end of the day.
Wanaie is away from the hustle and bustle (and traffic!) of Honolulu, and the beach next to the complex is gorgeous and never crowded. If you do want to go see the city sights, it's not that far, but you do want to have a rental car.
A few tips: Make sure the screen doors to the lanai are actually shut (they can be deceptive), especially when the sun starts to go down. The laundry room has no change machine. Only use the side-loading dryers in the laundry room, not the top loading one. Of course, it's possible that the dryer will be fixed by the time you go there, but residents told me it has been broken for a while and there is no sign on it and no change return, so if you don't see it working, don't use it.
Secondly, about Henrique. This guy is amazing. Always easy to get ahold of, super friendly, and helps you out with anything you might need. The day we were flying out we needed to return some swimming gear we rented, and although the sign said "Open Daily" and specifically listed Sunday hours, they were closed. We didn't know what we were going to do, but I got in contact with Henrique and he returned them for us the next day. He was so helpful during our stay, but also respected our privacy. Best of both worlds!
If you want a relaxing beach vacation, an amazing host, and an excellent vacation, you can't go wrong at Henrique's.
