This was our best-ever stay. The hosts communicated well, everything was set up perfectly, there is nothing I would change. The view is exactly what you see in the pictures, the sunrise is unbelievable. The condo is quiet, has good air conditioning, and various nice touches--for example, the clothes washer/dryer are a moderately high-end front-load unit that is very, very quiet.
This location was absolutely perfect for us. If you haven't been to the island before, I really think Kapa'a is the place to stay. Poipu? Touristy. Hanalei? Crowded. Kapa'a is the perfect base from which to launch your activities all over the island, and there are plenty of amenities. Coconut Market is a 4 minute walk for shopping and dining, and there are many other amenities that can be easily reached by foot. Within about an hour you can reach any place in the island that is reachable by car. We never waited for seating at a restaurant in Kapa'a, beach access was literally right out the door, and we had everything we needed or wanted. Just stellar!
