My fiance and I (he proposed in Kauai!!) stayed at the Kapaa Sands for 7 days. I have to say first that we stayed in condo 9, we chose it ourselves based on the reviews here, and the great help provided by the staff at Kapaa Sands. We chose it as it was a king bed, upstairs, and on the beach.
First - the location: the condos are almost on the beach, it was amazing sleeping with the sound of the ocean! Everything is within walking distance: a (very) small protected beach to snorkel, great restaurants (try the Japanese and the Mexican), shops for souvenir, and kayaking. We chose to stay in that area to be able to drive everywhere easily (35mn to Pipu, 45mn to Hanalei), and considering all the road works and speed limits, that was a great choice.
Second - the condo: there is no a/c, but a clever system that allows to keep the windows open so the air goes through easily, it is very efficient and we slept well. The kitchen was very well appointed, although we were surprised not to find any basic staple (no coffee or oil, no sugar, salt or pepper for instance). The lanai is fab, with a 180 degree view, fabulous!!!!
Third - the service: the ladies at reception were incredibly helpful for restaurants' recommendations, follow their advice. They also provided us with coolers so we could make our own lunches, and beach towels, which was very helpful. Only small negative is that our bed was not redone as planned as we had left our clothes on the bed, first time I hear of this rule anywhere! but not big deal overall.
Overall, we were thrilled to have stayed there, we stayed in a great place, with an amazing view, and managed to save some money by making our own b'fast and lunches, but in a romantic way (nothing beats breakfast on that lanai!).
I'd definitely go back, if only I could!!
