The location of the Coconut Cabana (and adjacent Pineapple Pad) were perfect. It's at the end of a road which is gate protected (to eliminate tourists and surfers) making it perfectly quiet. House is well equipped for cooking and BBQing, with the kitchen very well setup for that open air feeling.
It fit 4 adults and 2 kids comfortably, with the kitchen area good for when kids went to bed upstairs. Basic grocery shopping (i.e. not Walmart or Safeway) is ~10min away, so we did the "big shop" on our way up from Honolulu.
We barely saw and never heard the neighbors at the Pineapple Pad (although they may not say the same; we had a very fussy, overtired baby!).
The only tip I would suggest is because this home is right on the beach you really have to pay attention to instructions to keep floors/counters spotless and windows closed when you're not there. Even a couple crumbs (in the open or in a suitcase) will attract ants - it's part of beach living in Hawaii, I guess.
Overall, we would stay again in this area and consider this spot.
