We didn't realize how much we needed to stay at a place like this until we did. We live in Lake Forest Park right off of HWY 104 and we're constantly hearing sirens, car racing, and a variety of other noises regularly. Our cat is also fairly vocal.
This place is pretty remote. During the day we'd explore the Island or surrounding area, and in the afternoon/evening we found ourselves relaxing in the back yard with a book, and dinner from the grill.
Later in the evening we had the choice to hot tub or do a fire; hot tub won out the two nights we felt up to doing stuff. The hot tub is technically behind the owners garage, but the walking path to it is largely private, especially at night.
The amount of interaction you want to have with the owners seems to be largely up to you. We briefly talked to them in passing; on our way in our car to explore the island or walking down to check out the trails on the property, both while they were tending to horses or their garden. You can text them if you need anything during the stay, but we found that we didn't.
A LOT of the beach access on the island appears to be connected to private, gated communities. My wife can't walk very vary and as a result we didn't check out the community beach available to us, and the walk to Fudge Point State Park after driving to a secret spot (denoted in the guest book) was too far for her to finish as well.
Come for the forest and the tranquility it provides. These kinds of spaces are hard to find
