The place is pretty small, but had everything we needed.
The kitchenette corner is inside the closet and everything is really mini - there's barely space to put stuff. We could store there some ready to eat food, but regretted not having a full kitchen since the food on the north shore is really so so.
The sound insulation between this suite and the main house is pretty much non existent, keep in mind. Most of the time it was quite though, so we didn't have much problems, but we got lucky with the neighbors I guess.
There were some problems with the toilet and we had to use the pump a few times - despite we never flushed anything but toilet paper. Our time on Kauai was a bit hectic, so I only had time to let Bruce know after our stay - hopefully it is resolved.
Overall, I feel like the place is expensive for its value, but everything is expensive in this area.
