Resort was nice and quaint. Although the seaweed bloom is bad this year, there are plenty of things to do nearby and good dining options on the island. Staff was very helpful and accommodating.

Stayed 1 night

Stayed at Grassy Flats in the Keys recently and wanted to share an honest review since the online photos make it look nicer than the actual experience. The bad: the seaweed smell was rough during our stay, really stinky and hard to escape. Rooms were loud and the beds were creaky, so sleep was tough. The tiki bar was also disappointing, open bottles of liquor and simple syrups sitting out with no lids on them, which felt pretty unsanitary. The good: the staff was great, really friendly and helpful the whole time. The food at the market was genuinely great, organic and fresh. The fresh catch of the day sandwich from the market was honestly one of the best sandwiches I’ve ever had. Overall I probably wouldn’t go back, mainly because of how loud the rooms were. I’m sure it’s a nicer experience when the seaweed isn’t piled up, but between the noise and the tiki bar situation, it just didn’t match what the website promises.

Tv Remote didn’t work. Phone didn’t work. As a solo traveler didnt love that I couldnt reach the front desk. Calling from a cell phone, rang and rang then hung up. Had to go down to the front desk for anything needed. Beach amenities were non-existent. Restaurant completely ignored me when seated alone. 20 min with no one asking if wanted to order. Not a great experience and not worth the price!!!
