I had a wonderful stay at Coco-A, at The Fern Grotto Inn. The suite was immaculately clean, comfortable and spacious. There were plenty of towels and toiletries. The kitchen was well appointed. The suite has a private rear yard, and the (common) washer and dryer were new, well supplied and worked perfectly. There is plenty of parking. The wifi is excellent. The unit is air conditioned, but I didn’t need it. The ceiling fans were fine by themselves. The whole ambience is charming.
Although you can walk to the beach and the nearest shopping, the sidewalks are not that great. It’s also a long-ish walk to Kapa’a Town. I would happily stay there again, but next time I would rent a car. Also, the cell service in the suite is extremely spotty. But with those minor niggles, I highly recommend this place!
