This place is a gem! We visited after the Christmas holidays with our daughter and boyfriend. Nice large place, well appointed, with great places to hang out or find alone time, plus a fast walk to the fairly secluded beach and access to the back bay/river (having cayaks and paddleboards a real plus!). Kalihiwai Valley is off the main road so it's quiet and feels like you are "living like a local", and then also very close to Princeville and Hanalei for greats shops and restaurants - best of both.
We go to Kauai every year and would definitely return. Thanks Holly and team.
