We had a great stay at Marls' place in Poipu. The location is unbeatable. It's a 60 seconds walk to the beach. Both to Brennecke's which is great for boogie boarding as well as to Poipu Beach which is great for snorkeling and seeing the turtles come on shore.
The house is exactly as described. Straight forward and practical. Especially when you come back from the beach, you can shower outside and wash everything with a hose in the backyard. The inside was all clean and the kitchen has everything one needs.
Great stay and we loved it.
