We just contacted an agency and they gave us a code to get the key for the house. We did not have any other contact with the hosts.
The place met the description. You drive through a lot of vast golf courses before you get to this condo. There is nothing else walkable but the beach, so if you want to experience a town, this is not as nice as somewhere like Hanalei or Kapaa. But there is a real sense of privacy and being hidden away. In fact the beach is called "Hideaway."
