Top Grassy Key Hotel Reviews
Tranquility Bay Beachfront Hotel and Resort
10/10 Excellent
"Villa was clean. Staff was very polite, knowledgeable. There was a problem with the toilet and it was taken care of. A shower outside of the pool area would be very helpful in washing off sandy feet, also a door mat. Silverware was very cheap, could be better. It's the small things that could make it great."
Kingsail Resort
10/10 Excellent
"Buena ubicación, buen trato del personal, súper limpio. La unidad tiene cocina que es súper práctica. Lo único que no nos gustó fue que al estar hospedados en plata Baja escuchábamos todos los movimientos de los vecinos del piso superior"
Lime Tree Bay Resort
10/10 Excellent
"We always stay at Lime Tree Bay. If you find yourself driving down U.S. 1, be sure to stop and enjoy the Exceptional Service, Beauty, and one of the Best stays we have loved many times, in Layton, Lime Tree Bay and the Keys await you!"
Banana Bay Resort & Marina
8/10 Good
"This was our first time staying at Banana Bay resort in October 2026. We liked the cleanliness of our room, although the AC was a bit noisy the climate in the room was very comfortable. The front desk staff was super friendly and welcoming. At The Pointe Bar, we were able to experience the most beautiful sunsets, truly remarkable, it would had been more perfect if other options of cocktails were available outside of wine and beer. Additionally, there was No Music playing in the background, it would had been great for the completion of a perfect ambiance, unfortunately this was a miss for me. Breakfast was good, the bagels and pastries are a nice touch, we would had loved to have other options such as fresh fruits like bananas, oranges and apples available. The lighting on the entire property in the evening was a too dark to my liking. The parking lot area at the Island House was dark, we noticed there were no light posts in the vicinity. The entrance doors to the Island House stayed open all evening they did not lock (locks were broken). For safety reasons they should auto lock and access only with the card key readers."
Fairfield Inn & Suites by Marriott Marathon Florida Keys
10/10 Excellent
"The lunchtime waitress in the bar/restaurant was incredibly lively & full of drive. She really made our day. Room good size, clean & adequate."
Captain Pips Marina & Hideaway
10/10 Excellent
"The room was clean and smelled very good .The air was on when we came in ,so it was a good temperature as well .Staff was friendly and attentive ."
Coconut Cay Resort & Marina
10/10 Excellent
"muy recomendable muy buen servicio centrico"
Hawks Cay Resort
8/10 Good
"Our villa was right next to the workers building. Not an ideal spot for a “premium” villa. Also when they were cutting lawn and blowing leaves they were blowing everything all over our rental cars. Parking was tough because I think employees were also parking in guest spots. Again I think this was due to the location of our villa. We were never told what to do with our garbage or if housekeeping would come clean. Found out later you need to specifically request it 24 hrs in advance. It was off season so nice and quite not too many people so they definitely could have put us elsewhere. Other than that we really enjoyed ourselves and plan to go back next time we would just be specific on check in about the location they put us in."
