Disliked: Amenities, property conditions & facilities
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.

Inn was overpriced ($600/night) for what you get. Limited food options and expensive based on quality. Nowhere to pick up a quick sandwich or muffin or fruit or yogurt…The food service was VERY slow ( min of 1.5 hr every time). Our breakfast was cold and overcooked. After waiting, entree never arrived and they had run out. Hot tub was broken and staff had no idea when it would be fixed. Ac was overloaded and didn’t work on arrival. Website indicates yoga on Sundays but was not accurate. Inn is inland not directly on the water.

The property is beautiful and the staff is always pleasant and talkative. However, since checking out there was an extra charge added to my card of a little over $100. I reached out to the Cove and was asked to send an email providing proof. Three days passed and I called numerous times with no answer to my calls or email. During my stay I had issues where I was charged almost $600 but was told it was due to booking with a 3rd party (Expedia). While that issue was resolved before check out I was not informed of any other charges outside the resort fee for after check out.

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.
