Apparently Claudia is the host while Nick is the co-host, so my interactions were with Claudia, who was very prompt. The place looks better on the pictures then in person. At first we were a little skeptical, but then we realized that we had everything we needed and the mattress was comfortable. The road just outside the patio is heavy use in the morning and a dump truck passing over a speed bump close by made a loud sound. We were still on our time zone 3hr ahead, so we were awake by this time.
It was our first time on Kauai, so we did not know what area to stay at. Kapa'a town is not very plush, but you will see how locals live, and it is not crowded, and it has good places to eat. Little shopping village by the Plantation Hole is very nice.
Lydgate park is marked for swimming, but not many people were swimming there, we did not see kids there either. Strong waves can get far into the sand, so our towels got completely wet several times. The waves move huge tree trunks around, which was a cool sight. Fiji beach was calm and shallow. I found great coral specimens there. Wapoli park is where locals swim and picnic with clear and reasonably calm waters. From the Plantation Hole you can walk to all these beaches and beyond (not that far and passable), which we did and enjoyed it a lot. You will see homeless camps sprinkled in.
The bike path is great. Sleeping Giant trail is great. Find a stick to walk with. It is very slippery. Pack good hiking boots if you plan to hike in Kauai in October. They will get dirty.
Poipu is where it feels resorty: combed and much more crowded. We drove there for a swim and sun bathing. When it rained in Kapaa, it was dry in Poipu.
