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.

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.

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!!!

The staff was WONDERFUL! Receptive, responsive and so happy! They make your stay so special, everyone makes you feel like you are the only guest there! The bartender Jeff makes the BEST drinks, Lizzy and the office staff are all excellent. They know everything in the area that’s fun to do and the restaurants that serve the very best food. Audrey, Jasmine and the rest of the staff in the “Land & Sea Market” on the property was off the charts, 10/10 for awesome service and friendliness, and the food was consistently delicious and plentiful! The chefs were top notch. They make whatever you like and amend the dish as necessary. We wanted to eat every single meal there every day, but we knew we couldn’t because we had to experience other food while we were on our vacation. Grassy Flats has another location down the street 5 minutes away called Bongos, which is so much fun! It’s not a hotel, it’s a fun/party place with water sports and multiple bars, music, and once again, excellent food and bartenders! Jasmin was covering the bar the night we visited Bongos and her drinks are amazing! She is awesome, too! So friendly, so fun, and made us want to go to this fun party place every day! The one and only negative I would mention is that our room needed a little “TLC”. It was VERY CLEAN, which is the most important thing and all we care about. But, I do think it probably needs a couple of pieces of furniture that is in better shape but other than that, our experience was OUTSTANDING!
