Great place overall!
Lots of interesting stuff to do and easy access to the north and south of the island. Very easy and flexible check in. Kapaa can be a little busy on traffic because of the road work but will only cost you about a few minutes.
Good local restaurants to choose from, some very reachable by walking. Supermarket right across the street. You have great beaches to sunbath and relax nearby but also some where you can surf. Highly recommend renting a Kayak or SUP at Wailua River.
I would definitely recommend to stay at Stacey's place if you are going to Kauai!
