We enjoyed our stay and would gladly stay there again. We stayed in the adults section and it was quiet. Large room with great views over the water. Very clean and updated. Only negative was the bed was quite soft, not our preference, but comfortable. The bar area was lovely, and Marvin went out of his way to help you enjoy your time there. The property is north of Marathon proper, close to the Dolphin Research Center. The heated pool was wonderful, as we were there in March and allowed us to swim and not be cold. The hot tub was great.

The Grassy Key Resort service team is top notch! We were very impressed with every part of the property. Thank you for having the tiki bar open everyday. This was great being able to order anytime all day. The Grassy Key Land and Sea Market is on the property and the breakfast there was excellent everyday. The Rhum House was Great, this place is being run by professionals! Great food and service! This property is a little piece of heaven. Minutes from Marathon which is our overall favorite city in the keys.

The room and hotel are absolutely adorable. It's exactly what you think of when you think of the colorful places in the keys. It has covered parking. you're able to use the bikes around the property along with other amenities such as paddle boards. It has a separate area for families vs adults only. 2 pools, right off the water. Has bars and restaurants on site, plus near other restaurants. The room was so nice, with a cute balcony to sit and enjoy listening to the waves.

Following a long drive we received a great welcome from Morgan on reception, who eased us into the Grassy Flats vibe. The room (302) was outstanding, shotgun style, with 2 great Queen beds, plenty of space, good quality furnishings and clean. The bathroom was superb, 2 wash basins, a super large shower with built in seat, and then the balcony. A tremendous view so peaceful and relaxing. We ate breakfast from the diner on the balcony each day and the food was excellent

Andy

The location is such a pretty setting and you really can enjoy it because your room has a spacious lanai. There is a market on the site to get breakfast . The market also has many food items that you can buy.Every staff member from front desk, tiki bar,rooftop bar and delicious restaurant on site were GREAT. Almost left out that the rooftop bar had a wonderful happy hour and menu and music most nights.
