Coastal Maine contemporary cottage

Our cottage is meant to be both contemporary and rustic. It is where we go to get away from the hustle and bustle of the modern world and slow down. There is no TV or internet, even our phone is an old rotary one. You will see that we have a good radio, and games and books to read, and plenty of things to do outside. We hope you will take the time at our cottage to comfortably reconnect with yourself, and each other, while enjoying what Maine is renowned for, our quality of life.
