If you want a large, cheap place in Kauai and don't care too much about the details, this may be the place for you, but if you want a well-maintained property then maybe consider another location.
Pros: The house is large and every bedroom has an en-suit private bathroom, which was extremely nice with a large party of couples (8 of us total). The second floor deck looks out over the small yard and ocean, leaving excellent views and is a wonderful place to have breakfast, read a book, play cards, etc. In addition to a swing and hammock, it also has a fairly large table/chairs that accommodated our entire party. The downstairs, outdoor bar was a fun novelty and there is some green space that could be good for kids. The master bedroom also came with two children's beds, a pack-n-play, and a crib. There were some solid beach supplies (a few boogie boards, a shade structure, a few chairs) at the house and you are only a 1 minute drive to a nice beach for hanging out, just beware of the waves as they are quite aggressive and the current is very strong.
Cons: Communication and property details were definitely a downside. We had no check-in instructions prior to the trip, requiring that we reach out and try to get ahold of the property manager so we could have an address and access information. Thankfully airbnb support was able to assist us in getting that information before our party arrived. When we did arrive, at least one of the bathrooms hadn't been cleaned (the toilet bowl was stained, and the wall still had the residue of a smashed bug). One of the sinks was fully clogged, and another bathroom had a barely-attached towel rack that fell off the wall onto someone's toe. When we had the manager come by to check out the sink, he just ran some water and hoped it would eventually work itself out, leaving the sink clogged for the entirety of our stay. The kitchen was stocked haphazardly: only one old tired sponge, only one dish towel, only one giant mixing bowl, dull knives, mostly-destroyed cutting boards. There's an iron, but no ironing board anywhere in the house.
Apparently the last tenants had broken the dishwasher, but the property manager didn't tell us until we asked about the missing rack. This was particularly problematic as we were a large party who cooked almost exclusively at the house for our meals. The manager told us to run it anyway with just the one rack and to put a towel or two down under the dishwasher to contain the leak. He didn't address the dishwasher until the last day of our trip, and even then it still leaked. We ended up buying our own hand washing supplies and had him reimburse us for the cost.
Ultimately, we would be unlikely to spend another trip here. While the house was large, air conditioned, and had en-suite bathrooms, the many small issues, poor communication, and broken dishwasher were enough of a drawback for us to consider other places.
