Had a great stay at Nathalie's place. The location is very convenient to beaches on the north shore. The one thing I would note is that I didn't realize Princeville isn't really a town - just a collection of resorts - so restaurants/etc nearby are limited, and the road into Hanalei (the nearby town) was only open for limited hours due to construction.
The apartment itself is a great little studio with easy access to the resort pool / hot tub / tennis court. It was very clean, and check in was easy. I'd recommend this spot to any couples staying in the area!
