We LOVE Grassy Flats! This is our second time staying here and we will be back again!! Grassy flats has everything you want from a large resort such as dining options, water sports, multiple pools, a convenience market but with the laid back, quiet and quaint small beach resort vibes.

Marketed as a resort but it was disappointing compared to pictures. Entrance difficult to spot. Room was very nice except it was an accessible room so bathroom floor always soaked after showers. Staff all lovely, Wilma the cat visited our room . Pool is tiny and so much foliage. No real beach area available to sit on and do much debris on the beach that it was really very unappealing to try and swim or use kayak. Rhum House restaurant was excellent. The Grassy Flats convenience store for breakfast or lunch was great too. Didn’t rate the beach bar zero atmosphere snd mess that helpful lady working the bar.

It was a nice place, clean. We had a late check in (after 7pm). Instructions to get our keys were great, the instructions to get to our room were kind of difficult. The numbers on the building to get to our rooms did not match our instructions. The elevator stopped working, at breakfast they ran out of plates and utensils about half way through breakfast and were not able to find them.

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!!!

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.

Grassy Flats resort is a beautiful, private, secluded property. We felt so relaxed here. There is not much of a “beach” area but seeing the high and low tide reveal the “grassy flats” was so cool. There are beach chairs/lounge chairs everywhere (by pools and along ocean front) so you can post up wherever you want. The pool was awesome and shady. The restaurant The Rhum House was gorgeous and the food was excellent. The room was so beautifully decorated, and the balcony was wonderful. I would recommend this to anyone! And I already want to go back.
