Very quiet; the only noise was the ocean. The house was located on the beach, along a quiet dead-end street a few minutes from Port Angeles. From the large back yard, we could see Vancouver Island across the Salish Sea, not to mention more stars than I've seen in years and even the Milky Way, which I'm not sure I've ever seen. The house is within walking distance of the Elwah estuary, has a kitchen well-stocked with dishes, and is as clean and comfortable as you could want. All five of us were very happy with the selection and would very happily stay there again.
Oh, you want a downside so you know the review is real? Fine. The wifi is not fast, not awful, but not fast. You can live with that. You're on vacation. Put your phone down and enjoy being on the coast. :P
