Just finished eight days at Poipu Kai, and this condo was excellent. The location was outstanding and the complex was beautiful. Susan was a fantastic hostess, always available to answer questions. Three bedrooms and 2 1/2 bathrooms make this perfect for families. The beds are comfortable and the complex is quiet at night. A very nice pool and spa, along with grills, are close by.
The beach is about a 10-minute walk, but it's through a well-landscaped complex with beautiful views toward the water, so nothing to worry about. The waters right at the beach have green sea turtles and many kinds of fish for snorkeling. It's like swimming in an aquarium.
The picky downsides: no A/C, but opening windows and allowing tradewinds and ceiling fans to do their work mitigated the issue for us; two of the bedrooms have vaulted ceilings so there is little space between the ceiling and roof, so if it rains hard at night as it did for us once, it can be hard to sleep because of the pounding noise; the living room couch is uncomfortable.
Overall, I highly recommend this place for a visit to Kauai, if you plan to stay on the south side of the island.
