We really enjoyed staying at Susan's roomy condo in Kapa'a. It was clean, well-stocked, and wonderfully located. The lanai directly faces sunrise over the ocean, making morning coffee an exquisite experience. Especially when the personable chickens endemic to Kauai share it with you.
Many of the restaurants and shops on Kapa'a's main drag are within a block of this condo--there's a lot you can do without getting into a car.
One of my favorite features was Kapa'a's highest-rated bike rental, Hele, within that one-block walk and a paved 4-mile hike/bike path that runs up the windward coast of the island. The path is adjacent to this condo's back yard. The path is an easy, breezy ride, and the views are spectacular.
The Pono Kai resort, to which this property belongs, is also a great home base. It has immaculately manicured grounds, a peaceful pool, koi ponds, hammocks, grills, and several outdoor activities like croquet or lawn chess.
This was our first trip to Kauai, but we're sure to return, and will see if Susan's property is available then. Mahalo!
