Beautiful conversion of an old military facility to a hotel. Great pool area. Spacious, clean, confortable room. Nature surrounds with walking trails. Food OK, but could be improved to match the remainder of the experience. Fun to ride ferry to the island.

Great hotel and lovely experience
Hotel was amazing, as were the restaurants and facilities. Very quaint, yet luxurious. They weren’t fully staffed yet, but they helped us any way we asked them to. Would definitely do it again.

6/10 Good

Puzzled with this place. Very limited and expensive dinning. Felt like The Shinning because of isolation. Once you're there you're stuck there. Understaffed even though it wasn't busy. Clean..nice room, although in room fireplace inop.

10/10 Exceptional

A beautiful, quiet, oasis in the middle of Casco bay. I had the joy of staying at this property for four days. I love the ambiance, atmosphere, and the tranquility this place offers. The staff was so polite and made our stay so much better. I highly recommend!
Sean, 4-night trip

10/10 Exceptional

Charming Inn, wonderful staff and quiet, peaceful surroundings. Our suite was amazing, very spacious, tastefully decorated and had everything we needed. The AC and heating system wasn’t working for our entire stay, how we, the temperate climate and cool nights made that a non-issue, Loved every minute!

Beautiful hotel on the island! Staff were warm and welcoming!
Margaret, 1-night trip

Lacking in hospitality
After we walked up a hill to the Inn with our kids and all our stuff, we were told “sorry” for not picking us up and then made to wait an hour (including having to feed baby in lobby) while they tried to find our reservation (while blaming us for booking through hotels.com). Once checked in, the rest of our stay was fine. Food from the restaurant at the hotel was very average - edible but would not recommend or return.
Meredith, 1-night trip

6/10 Good

Beautiful But Over Priced
Very misleading Thought that the hotel was near the water Pictures that were shown made you think that the hotel was near the water but it was a walk over the hill, walk to the beaches were over the hill Very secluded and very quite Hotel is centered in the middle of an old army barracks Food was very expensive and average for the price A lot of walking The ferry schedule is very limited in September unless you want to walk 15 to 20 minutes over the hill to the other Ferry stop Over priced!!
Mark, 4-night trip

Amazing getaway !! This island and the hotel was the perfect vacation we needed!
valerie, 2-night trip

8/10 Very good

We had a great stay! And everyone was very nice! And it was Beautiful and peaceful!! The only thing I will say is if you have to leave early arrange transport to the ferry the night before because the front desk is not open early, And calling the number went straight to voice mail. Also, coffee in the morning was not easily accessible. Will definitely go back… and I will take extra keurig pods ☕️
Randimae, 4-night trip

The staff was very pleasant and our room was very nice.
Jonathan, 3-night trip

10/10 Exceptional

The parking in the city was difficult and expensive. The Foggs ferry to the island was good. The hotel and grounds beautifully kept. The food was not all that good for me (linguini and clams) but my wife enjoyed her dish (cod fish sandwich). Bar drinks were expensive.
