I stayed at the Captain's Quarters for a week with 3 friends, and everything about it was great for us, we loved the house. The two bedrooms were a comfy fit for the 4 of us, and we're a finicky bunch :). The kitchen is large and updated and perfect for cooking and hanging out. And the outdoor space is also large and comfy. I, personally, loved the outdoor showers.
We didn't spend too much time in the immediate area, but the location was perfect for exploring the island. Swimming beaches are bikeable/walkable from the house, and Poipu is only a lovely 40 or so minute walk away. It's a short walk down to stroll along the water to watch the sunset, and we went to a few very good (higher end) nearby restaurants on the beach. The neighborhood is also beautiful and a great place for a morning or evening walk.
Our host, Dani's daughter, was so sweet and great about checking on us to make sure we had everything we needed and see if we had any questions. Responsiveness and accessibility is definitely outstanding here, much appreciated!
