Summary: The room was outstanding. The view was absolutely gorgeous. We were on the same floor as the entertainment/bar, but the noise was minimal and stopped at a reasonable hour. Parking was convenient too. The staff on the front desk were always kind. The house cat, Wilma, is awesome. If there was any room for improvement would be to regularly check the espresso machine. Ours had issues. A K-cup type coffee maker would have been preferred and should be easier to maintain. But there is a small store on the property that had good coffee. Overall, I would highly recommend this location. Very convenient to the Keys whether West or East.
