About this property

The Optimist Guesthouse 4 - Downtown loft - gym, sauna, deck on the river

Wake in this stylish and cozy apartment to the sound of the Megunticook River flowing by as you contemplate the day's adventures in Camden. In the heart of downtown in the historic Knox Mill, The Optimist Guesthouse is perfect for travelers seeking a vibrant weekend getaway or an extended coastal adventure. The breezy balcony overlooking the river provides a peaceful spot to relax or enjoy a meal. The shared gym features an infrared sauna for ultimate relaxation.
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.
During your stay at this hotel, you're just a quick walk from Camden Opera House. You'll find features like a gym.
  • Onsite recreation includes a gym
  • Just a 3-minute walk from Camden Opera House and 4 minutes by foot from High Street Historic District
