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!

My expectations for Grassy Flats was so high. It is a beautiful setting and the rooms are wonderful with excellent service from all staff . I would have rated excellent had it been for a few details . I was unaware when I booked months back that the rooftop bar and Rhum House Restaurant would only open from Thursday to Sunday . We arrived Tuesday and left Friday. So we ate at the Land and sea Market on our 1st evening - laid back, tasty food. The resort came to life on Thursday and both the bar and restaurant were perfect venues to enjoy the setting , such a shame we only had one night to experience this. The food at The Rhum House restaurant was simply outstanding, with our server Max who was one of the best , her knowledge of the food was spot on and she really looked after us . Great decor and ambience too. The other reasons for not an excellent rating are purely my own opinions . I found the rooms had little soundproofing, so as a light sleeper I was woken a lot and I struggled with the noise of the fridge next to the bed . However, the suite with the claw set freestanding bath was very luxurious with a lovely sea view . Just a little note to the resort - there was nowhere in the bathroom to store all toiletries etc. a small table or shelf would have been great . Jeff at the poolside bar was a great asset always cheery and accommodating with cocktails and ice . We loved the pedal kayak for 2 a great way to explore the bay . Thank you to all at Grassy Flats .

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.
