Our stay in the Coco A unit at Fern Grotto Inn was one of the highlights of our Kauai vacation. Why would I state that? Well, for starters, the grounds are amazing. Paul has gardeners that are constantly upkeeping his immaculate gardens. The facilities are top notch and include use of bikes and kayaks as well as all the beach necessities. We used the kayaks and were able to start paddling literally 10 ft from where they are stored.
The location is centrally located with a 45-minute drive to the north side of the island and a bit longer drive to the west side. There are plenty of activities in the immediate location but Costco/Walmart, etc are not too far away. The bed was very comfortable affording us a good night's sleep after the day's activities. The A/C works great, but we did not have to put it to use much as there were ample windows to allow good air flow.
Some reviews complained about road noise or roosters crowing. We were not bothered by either. Rating it a 10/10
