5 / 5

Very beautiful and quaint cabins near everything . Cozy, quite (even though it is near the main road to Acadia NP) . Very clean and all you need to rest you bones for several days. Sitting outside on the Adirondack chairs eating breakfast and just relaxing with a fresh cup of coffee from the office.

The owner Dan is super nice guy. Literally makes you feel at home. We stayed in a suite in the main house. Very cozy and cute, exactly what we'd expect and wanted for this specific trip. They also have cottages available, a hot tub on site, yard games, fire pit and nearby dining.

We enjoyed the stay. The room was very cozy. It was clean. The beds were comfortable. I would definitely stay again. The only thing is to look for the heater unit on the wall. It was a little chilly! Once we found it- it worked great!
