If we could give Marion 6 stars, we would. We stayed for 9 days on a couples vacation. The room was clean and pretty. Marion's back-yard is beautiful and peaceful to wake up to. You can get to the beach in the blink of an eye, and Montara beach (the one within walking distance) turned out to be in our opinion, the best beach we went to for the whole vacation.
One thing that other reviewers didn't mention is that living in a beach town means that you are almost always driving against traffic. I think we only hit about ~20 minutes of traffic for the whole 9 day stay! It's a quick 30 minutes to most parts of SF and the drive is beautiful the whole way.
Marion as a host was very responsive. When there was an air quality alert due to the wildfires, she reached out to us to make sure we knew, and of course she had an air purifier already in the room. She was ready with whatever we needed, but wasn't intrusive. With the fan on as a white noise machine, we weren't bothered by noise from Marion's side of the house. Her dog gave out the occasional bark but nothing at all problematic. When we ran into her and the dog outside the house on walks or in the back year, the dog was friendly and loveable - it felt like an extra!
