Top Grassy Key Hotel Reviews

Hampton Inn Marathon - Florida Keys

10/10 Excellent

"We spent 5 nights . As a family of 3 with our 11yr old son! Everyone was extremely wonderful. Beds need a serious upgrade!!!!! Pool was great, hot breakfast, TV / Game/ Little Library room is wonderful! Overall great! Only reason we wouldn’t be back is because of the beds :)"

Fairfield Inn & Suites by Marriott Marathon Florida Keys

10/10 Excellent

"We loved our stay here. We had a beautiful room with an amazing view of the ocean and the pool. Everything was super clean everywhere! It was extremely well kept. The complementary breakfast was amazing in the morning. And the little store has everything you need. The little gift shop was great as well the restaurant under the tiki hut was delicious too! I highly recommend this place two pools open till 10 PM jet ski boating fishing and right across the street from the hotel we saw the most amazing Key West sunsets every day we were there! We will most definitely stay there again."

Kingsail Resort

10/10 Excellent

"Great Stay Everytime! We stay at the Kingsail about 3 times per year. The rooms are Always clean, Staff is Excellent, Great views of Lagoon, Kyacks, Pool, is impeccable, and more! Reasonable rates, Great location. We caught our biggest fish right off the dock! Big shout out to Derek, and staff for a great time! Thanks again!"

Rainbow Bend Resort

8/10 Good

"Nice place. Staff were very helpful and friendly. Rooms are clean and comfortable. AC worked very well. Full breakfast provided 8am-10am with a limited menu. Kayaks and bikes available. Unfortunately there was a lot of seaweed on the water. Pool and hot tub worked but only accessible until 8pm. Parking was free and adequate. I would recommend."

Lime Tree Bay Resort

10/10 Excellent

"We had a wonderful stay and were thoroughly impressed with the property from start to finish. Our room was cozy, comfortable, and exceptionally clean, with a bed that made it easy to relax after a day in the sun. The amenities truly set this resort apart. We enjoyed having access to kayaking, snorkeling, and fishing, all conveniently available on-site. The pool area was beautifully maintained, with comfortable cabana-style seating that created a relaxing atmosphere. The beach was equally impressive, offering plenty of shaded spots to unwind and some truly breathtaking sunsets each evening. One of the highlights of our stay was the staff. Every team member we encountered was genuinely friendly, welcoming, and eager to help. Our teens were excited to use activities and games available, making it easy for everyone to stay entertained. The entire property was meticulously maintained, and it was clear that great care is taken to keep the grounds looking beautiful. We also appreciated the convenient parking located directly behind the building and the on-site restaurant, which made dining easy with breakfast, lunch, and dinner options available. If I had to mention one small area for improvement, it would be the coffee. Everything else exceeded expectations, but a better cup of coffee would make the experience absolutely perfect! Overall, this was a fantastic stay, and we would happily return and recommend this resort to others looking for a relaxing, well-maintained getaway."
