We have rented various properties around MDI for the past 10 years, and Sea Breezes was the best.
Located in Tremont, the area is quiet and out of the crowded "Ellsworth - Bar Harbor" corridor. And even though we had longer car rides to the east side trails and attractions, the car rides were beautiful traveling through Mount Desert Island.
Locally, we found excellent restaurants around the Bass Harbor area, and a convenient IGA grocery store in Southwest Harbor. That said, we recommend buying groceries for the week in Ellsworth on your way in, for better variety and cheaper prices.
A unique feature of this house is that it is on the tidal bay, so every 6 hours you either see water or mud flats. We are "birders", so we enjoyed watching the birds feed at low tide, and enjoyed kayaking (with the complimentary kayaks) at high tide.
We had 3 adults, and the house was roomy, clean, and comfortable. The grounds around the house had hammocks, and had a "resort" feel. Very nice!
We had a few interactions with Stacy, and she was responsive, and quickly answered our questions.
We really enjoyed staying in Sea Breezes, and hope to return.
