Grassy flats resort and beach club in marathon Florida is an absolute gem! Most of the rooms have a tranquil beautiful blue Altantic view and are very clean. The staff is attentive and hospitable. It has several restaurants with amazing food options. It has two pools, one for families and one adult pool. There are also many activities right on site like kiteboarding. I highly recommend this gem of a resort!

We had an amazing stay! The property was beautiful. The breeze was amazing! We loved the option between a hot tub and pool and the face that you had a couple of restaurants on site was amazing! I love to run and there is a bike and walking trail right across from the resort. We had an amazing time. The only thing I would change would be sometimes the smell from the ocean not being up...other than that it was an amazing stay!

Nice quiet stay. Pools were nice. Beach is advertised but not really usable for swimming, snorkeling, etc. The bathtub faucet didn’t work and our air conditioner wasn’t functioning properly - it was always 75-76 degrees inside, which made for uncomfortable sleep. We were told maintenance would come, but they never did. Ceiling fans would have been helpful. Beds were just okay.

We were on our honeymoon. We had a very nice relaxing trip. The pool was clean, the view was great, and the service excellent. The location was ideal. It was a short drive to everything we wanted to do. All the lady’s at the front desk were so helpful and gave us must see spots. But we were able to come back to a beautiful and calm room. We stayed on the top floor and had a great view of the ocean.

Great family vaca!

What a great stay we had! Our first time in the keys and it was fantastic! We booked 2 nights initially but after spending time at the tiki bar with Jeff while waiting for our room and watching the kite surfers, we booked a 3rd night. The front desk staff was very accommodating and kind and Joe the tiki bar bartender made great tropical drinks and played incredible music. We are already plotting our next vacation here!

The rooms are beautiful. Kudos to the interior designer. However, the restaurants and bars were closed. Only lukewarm water in the showers. Our a/c broke and we had to change rooms. No room cleaning or fresh towels provided. Receptionist not friendly or inviting. Beach full of seaweed with a smell that permeated the hotel (not the hotels fault) but not pleasant for guests just the same. It was our second visit. We won't be going back.
