We recently spent a week in the carriage house and thoroughly enjoyed our stay. The apartment was well-stocked, with lots of towels, china, pots, etc. The location was perfect for us, just outside Damariscotta and a short drive to our friends in S. Bristol. I loved sleeping in the cool night air with the windows open - bring pants, socks and a sweater!
We loved Damariscotta - it's a great little town with a fabulous bookstore/cafe/toy shop, restaurants, a seafood market, a used bookstore, a theater, and two Reny's department stores. The produce from the Monday afternoon farmer's market was amazing. My husband could have spent the entire week in the town itself (especially at the soda fountain counter in Reny's!). We enjoyed it more than Wiscassit which I found too crowded with tourists and traffic.
My four-year-old enjoyed hunting for fresh eggs in the owners' chicken coop, playing on nearby Pemaquid Beach, and countless ice cream cones (try the shop in New Harbor). The library and children's playroom at the Damariscotta Library was a godsend when it rained one day. (There are also playgrounds next to Damariscotta's YMCA and in S. Bristol by the library.) If you have little kids needing a break in Wiscassit, check out their nice library with a small play area, too, as well as the large toy shop by the bridge.
For those who visit historical houses like us, we had a great tour of the Chapman House in Damariscotta. Unfortunately, we missed tours at the Wiscassit sites because they had limited hours during the week, so call ahead to confirm tour times. A visit to Portland (great children's museum) was an easy day-trip. At night with no traffic you can make the trip in an hour, add thirty to sixty minutes longer during the day.
