We stayed 4 nights at the Rainforest Jungle Cottage and during this time we were very pleased with the flat and its surroundings. The view of Kaneohe bay was quite stunning and letting the birds wake you up was very relaxing.
Kris left us some area's restaurant suggestions and you can trust it: the ones we tried were delicious.
Lanikai beach (and Kailua) is 10min drive and access to Makapuu beach and Hanauma Bay Nature Preserve is easy.
I definitely recommend this place!
