“My friends and I wanted to check out this hotel as the website looks fabulous.... We arrived on Friday and the grounds were breathtaking and our room is beautiful and comfortable. One of the highlights was the service... Brian one of the staff had helped us with any questions we had and delivered our drinks/food went above and beyond.. It made our stay great...he really wanted to ensure our stay was pleasant. It's nice to have beautiful grounds but it makes it even better when the service is great. Brian went above and beyond to ensure we had a pleasant stay.

““Hidden Gem”
My friends heard about Great Diamond Island in Casco Bay, Maine. It is one of the many islands reached by ferry from Portland. Part of the island is Diamond Cove, the site of an old army barracks. The barracks have been restored into beautiful condos and there are other private residences on this part of the island. The Inn at Diamond Cove is also a restored army barracks. The Inn is 5 star with a beautiful lobby with bar and fireplace and seating inside and outside for breakfast or dinner. There is a heated outdoor pool and hot tub and fire pit, wonderful after a day of hiking around the island. We were in a bi-level suite with fireplaced living room and kitchenette. Downstairs two king bedrooms with baths. Wonderful comfortable seating on a private porch. The Inn has golf cards to help guests get around the island if needed. Warm, friendly, and very helpful staff.“

““An Excellent Weekend Getaway”

My wife and I spent a delightful weekend at the Inn at Diamond Cove. It was their final weekend of the season and the weather was marginal (light rain) but we still had a terrific time. The staff was very friendly and attentive, Great Diamond Island is fascinating and wonderfully quiet.“
