Our stay at the Grassy Flats Resort & Beach Club was outstanding. Superb location & grounds, facilities and staff. Two great dining options, the Palm Deck outdoors casual and the Rhum House indoors, upscale and also with a great Ocean view. The Market next door was extremely convenient for breakfast, lunch option. Lastly, the "house cat" Wilma roaming the grounds is a real sweety!

The pool and pool area was nice. We liked how there was a separate adult pool from the kids pool. Also, the room was clean and had clean towels everyday. But, they allow dogs which was not a pleasant experience. Yipey dogs during the day & night was very disturbing and annoying.

Our room was absolutely spotless and was cleaned and remade each day were guests at Grassy Flats. The peacefulness of the property was what sold me to book our stay - we could not have been happier with this aspect! Every single member of the staff we encountered seemed concerned with us like we were the only guests on the property and our comfort and satisfaction were the most important things. After our stay, my wife and I have decided this will be an annual vacation for us!

We loved this resort. It is a great location as you can go anywhere to do things in the Keys in an hour or so. Our room was great, and the view from the patio looking through the palm trees was fantastic. The staff was friendly and helpful. The weather turned cold and we were not able to take advantage of the ocean, but the pool was heated nicely and we enjoyed it.
