Great staff service. Very high quality private stay. Amazing room. Also a really lovely historic tour too.

The hotel is over priced for what it is. Pool wasn’t clean and peeling paint. The rooms were nice, balcony is shared which was ok. It was beginning of the season so no one really knew who was doing what. Drinks weren’t good but I think they are struggling to get help. There is no where to buy anything outside of candy, icecream and small alcohol section. Lunch by the pool was simple but nice.

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.

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.

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!

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!

it was an amazing trip and excellent stay. Rooms were comfortable and excellent service. There are few dining options on the island but food was great at all. I will definitely recommend a short stay at the Diamond Inn.

Our stay at the inn was one of a kind. The location is gorgeous and we loved escaping the hustle and bustle of Portland for a relaxing evening on the island. Highly recommend!

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.

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.
