The Optimist Guesthouse is owned and operated by Evan and Ryan, childhood friends who grew up together enjoying all that Camden has to offer. As the owners of The Optimist Guesthouse we enjoy providing cozy, stylish accommodations and sharing the beauty of the MidCoast with our guests.

Nestled in Camden’s historic Knox Mill, The Optimist Guesthouse offers a refined retreat in the heart of town. Awaken to the gentle murmur of the Megunticook River flowing past, savoring moments of tranquility on your breezy balcony—perfect for quiet reflection or intimate dining. Unwind in the convenient shared gym, complete with an infrared sauna. A sophisticated haven, The Optimist Guesthouse exudes calm and yet is just steps from all that bustling Camden has to offer. The Optimist Guesthouse is located in the Knox Mill, a historic woolen mill built in the mid 1800s along the Megunticook River in downtown Camden, Maine. Operational until 1988, the mill specialized in producing wool felt. The Optimist's balcony looks over the scenic Megunticook River as it flows into town. The Optimist Guesthouse consists of five apartments, a lobby area, and a small, shared gym room with infrared sauna. Down the hall you'll find our friends at 40 Paper Bistro & Bar, a delicious local eatery. Across the bridge you'll find The Jack bar and restaurant, and just up or down the street will bring you to more options. Being a retrofit of a historic building on a slab foundation, the plumbing is on a pump system, which you will hear when using water.
