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.

Good to know

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.

Excellent stay. Room was incredibly clean and did not smell like toxic cleaning chemicals. Great bathroom, incredible bed, linens, sheets, etc. (some of the best). Hosts were VERY responsive as well. I would surely stay again. This is what I expect from an AirBNB!

My sister and I had the best impromptu trip to Camden. We loved Ryan’s place. It was so convenient and beautiful. Love how close it was to the restaurant 40 Paper. Everything was lovely!

This was our first visit to Camden and we couldn’t have been happier with our accommodations for our Christmas getaway. The kitchenette gave us everything we needed to prepare a breakfast and keep drinks/leftovers cold. Very clean, walking distance to everything and comfortable bed/couch. Our very well behaved dog felt right at home In this space. Would book again, 5 stars!!!
