Visiting in January from Oregon, we really wanted some sunshine. But everyone said the north area was prettiest on Kauai. We decided to split - 5 days north and 5 days in Poipu. Turned out, this was the perfect location for the rainstorms that came, with DVDs ranging from South Pacific to The Descendants, and a gorgeous view with covered balconies. When the sun came out there was pickleball, tennis and a small but pretty pool.
We'd also been warned to expect all kinds of crawly things, but the place was spotless and we only saw one lone gecko on the balcony. Nothing inside.
The furnishings were tasteful and of high quality. There were lots of thoughtful touches -- guidebooks, bird books, fish books, Elvis on Kauai, etc. Baskets to organize our stuff. Beach chairs and a boogie board, etc. (Put the beach chairs right into your rental car when you arrive. You'll need them!)
This is definitely a high-end place (with a price to match). Worth it.
