Overall location is relatively secluded, located in a quiet neighborhood about halfway between Hanalei/Princeville and Kapaa. Not a lot of great food options nearby, so expect to drive to Kapaa or Kilauea if you're looking for something to eat.
Gilligan's is on a shared property with another house, which is out of sight behind some trees but definitely within hearing distance, as we could hear our neighbors talking several times during our stay.
Soap and shampoo were strangely not provided, and we didn't realize until we checked in and had to make a quick run to the shops. Some of the bath towels also smelled of mildew.
Moloaa Beach is a short walk down the road and is a nice, quiet beach without too many visitors. Not really a snorkeling spot, although the tide pools had some crabs and fish.
