This property was fantastic for our family of 10. The views over the harbor were beautiful and most every room had picturesque views. Amenities were good. There is no central AC, but each bedroom has its own AC unit.
The only downside of the location was the drive time from the property to Bar Harbor and Acadia National Park. It took nearly an hour to get to those locations. Be aware that Sullivan has limited restaurants. However, we cooked several meals at the property. There was also a small outdoor grill to cook up some burgers. Personally I did not mind the drive, as it was nice to have a quiet, private space for our family.
