We have stayed in the one bedroom condo twice now, August's 2013 and 2014. We loved it! The accommodations are well appointed, clean, and quiet.
Boothbay Harbor is a busy tourist town, and there's plenty to do. The condos are in an area away from the main part of the harbor, on a separate Cove. It's quiet and peaceful. There's a nice deck to sit on with views of Mill Cove, yard with picnic table, gas grill, and fire pit.
Local things that we enjoyed doing include swimming at several local swimming areas, visiting lighthouses, renting standup paddle boards in the harbor (easier than we thought it would be), and visiting the Maine coastal botanical gardens. We took an evening sailing cruise on the schooner Eastwind and visited other local towns for day trips. There are plenty of restaurants in Boothbay Harbor that are friendly to gluten-free or people with food allergies. Each time we stayed for a week in Boothbay Harbor, we also visited Bar Harbor and Acadia for a couple of days midweek (three hours up the coast).
We can also echo the other reviewer's comments on the gracious hosts, Karen and Julie. They greeted us with flowers and a basket of goodies.
