Excellent location, about 5 minutes walk from Brennecke's Beach (good for boogie boarding - locals call it "Break Neck" as the surf is a bit rough) and 10 minutes from Poipu Beach (good for snorkeling, swimming, and general beach activities). Some restaurants in walking distance, and lots in short driving range (5-10 minutes).
Very quiet on the bedroom end, but there is a little sound bleed-through on the kitchen/dining area.
Unit has pretty much everything you need, and the A/C is a godsend, even in somewhat milder May. Separate A/C units in each bedroom and in the living area. The couch is very comfortable and great for post-beach naps.
No ocean view, but the garden is very lush, vibrant, and again, quiet.
Would definitely stay there again.
