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!

This hotel is an excellent option for a stay in the Keys. The restaurant might be the best you will find in the Keys, with an outstanding kitchen, great atmosphere and on the water. The rooms are very comfortable; you will need to ask for service, otherwise they will leave you alone. Great balconies overlooking the water.

We loved Grassy Flats! Our room overlooked the pool and ocean - our view was breathtaking! The entire property was lush and felt like a resort. We popped over to the market both mornings for breakfast - delicious! Our servers were very friendly, making our experience very pleasant. The rooftop bar patio was a nice place to land at night. Our 2-day stay was very relaxing and peaceful. And, the adult pool area was a great bonus. We would definitely stay there again!!!

We loved the property's options for things to do—paddleboarding, kayaking, multiple water sports, and bikes. The pools are very nice and relaxing. The room we had was spectacular and had an ocean view. The Rhum House had delicious food. It was overall a great experience and we hope to return soon.

The smell was very disapponiting i know its out of the control of the hotel. But it was hard to enjoy the outdoors. As for the hotel it had a very musky smell and i had to switch rooms. They did put me in a bigger room and it smelled better however was older looking needs work and updating. I did not recieve silver benefits all at.

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.
