We have stayed at the Beach house several times, and it is - hands-down - our favorite place to stay on the Monterey Peninsula. It's very spacious for two people. It's decorated and appointed like a real home, rather than a rental. (Note the Viking range.) It's very comfortable and easy walking distance to restaurants in Pacific Grove as well as a short walk to the Monterey Bay Aquarium.
If the Beach house isn't available when we want to go to Pacific Grove, we reschedule our trip.
