This is a roomy apartment, but perhaps a bit pricey for what you get. As other visitors have commented, the living room and kitchen area is spacious, and the view through the big windows is wonderful. The bedroom is quite small, and when the Murphy bed is down, there is less than 10'' of space between the corner of the bed and the wall that you have to traverse to access the bathroom or the front entry. This situation is made worse by a flat panel TV that is on that same wall and that you have to bend around to avoid hitting. There is a second bathroom and shower that can be accessed from the living room; its toilet is quite low, which is probably good for kids.
Ocean surf, wind, rain, traffic and a pump-like noise (sump pump?) made the apartment fairly noisy for sleeping, but that noise was otherwise not particularly noticeable.
The comfy couches and nice decor create a nice place to relax after returning from your island adventures. The location is exceptional, just a few feet from the surf. Also, Hau'ula is in a perfect spot to explore the windward side and the north shore of Oahu.
