Stayed here for an extended weekend during the Fall, and was extremely glad I did. Rooms were immaculately clean, food was delicious, and owner was extremely helpful and friendly.
The owner helped us with everything - directions to the ferry, picking us up at the landing, and then suggesting things to do - although we were there strictly to unwind for a few days. The beautiful view of the bay from our room (ask for one of the 2 front rooms) was an unexpected bonus. The island is quite a throwback, and was perfect if you are looking for a relaxing time hiking, laying out on the beach, or just stuffing your face with lobster! (You can get anywhere on the island on foot, but the Inn provides bikes if desired - your car is left back on the mainland!)
I highly recommend this place, especially if you live in the area and just want to get away from it all for a quiet weekend.
BTW, I found out during my stay that this is now the only open and available B&B/Inn on Chebeague, as all the others listed on TA have closed.
