Recent Reviews in Grassy Key

Hampton Inn Marathon - Florida Keys

10/10 Excellent

"Great location for Marathon. Near the main road but no audible road noises. Not the cheapest hotel for quality of the rooms but we were very satisfied. 1 hour drive from Key West and a few hours from Miami. We initially planned 2 nights before moving to another area but decided we were comfortable here and booked an extra 2 nights. We got to keep the same room too. Complimentary washing facilities which was very useful and appreciated. Breakfast was good for a continental breakfast. Disappointed that they used disposable cutlery, plates, bowls etc, had apples wrapped in plastic, plastic cups wrapped in plastic. Might be just the way things are done in the US but was very wasteful and not good for the environment. We had a spacious big room with 2 queen beds and a walk out balcony which we could access our car from as it was on the ground floor. Room needs a fresh coat of paint. Air con was working but the unit was a bit noisy! Pool was nice and quiet. Gym had good quality equipment."
