This is a fabulous place and we highly recommend it.
The great: the location is outstanding. It is a freestanding little house (or bungalow) that is a 1 min walk to beautiful ocean views and a 10 min walk to a small, protected beach perfect for swimming and snorkeling. The place was SPOTLESSLY clean, the decorations tasteful and colors cheerful, and the beds very comfortable. It was a bit off the road so it was very quiet, and from the backyard very private. The kitchen was fully equipped and the furniture comfortable. The Princeville area is very nice, and you are close to Hanalei, Kilauea, parks, hiking opportunities, numerous beaches, and the NaPali coast. While we spent most of our time on north side of the island, going to the south side was not a big deal (Lihue 45 - min to 1 hour, Waimea Canyon - 2 hours). The property managers are very friendly and responsive.
The house is a little worn around the edges in places, but being 100 yards from the ocean causes a lot of wear from the elements. Geckos - we understand that this is normal for Kauai to have them in the house, but it took some getting used to! The place can be hard to find in the dark (especially in the rain), so plan accordingly. They are many units that look the same, and most are not marked with an address. Also, do not shut the sliding glass doors while on the decks as they lock automatically. Ask us how we found this out!
All in all this is a wonderful place to stay and we would recommend it highly.
