Top Grassy Key Hotel Reviews

Fairfield Inn & Suites by Marriott Marathon Florida Keys

10/10 Excellent

"Las habitaciones estaban limpias, al igual que el hotel. El personal atento en general bueno"

Tranquility Bay Beachfront Hotel and Resort

10/10 Excellent

"Our stay at Tranquility Bay Resort in Marathon, Florida was truly excellent. From the moment we arrived, the staff made us feel welcome with their friendly, professional, and attentive service. The resort is beautifully maintained, offering a peaceful atmosphere, comfortable accommodations, and stunning waterfront views. We also appreciated the hotel's well-managed policies, which help maintain a quiet, safe, and relaxing environment for all guests. It's clear that the resort values both guest comfort and quality service, creating an enjoyable experience from start to finish. The grounds are immaculate, the pools are clean and inviting, and the private beach is the perfect place to unwind. Every detail contributed to a memorable stay. If you're looking for a beautiful, peaceful getaway in the Florida Keys with exceptional hospitality and high standards, I highly recommend Tranquility Bay Resort. We had an outstanding experience and look forward to returning."

Faro Blanco Resort Marathon Florida Keys, Curio by Hilton

10/10 Excellent

"This is the second time I've been to this hotel and surely I will be back. The property is just gorgeous and so user friendly. The pool by the ocean is great if you want to chat with other guests, have a drink and listen to mellow live music in a true Florida Keys way. The back pool is great if you want some privacy. The hotel is situated so you can actually walk places if you want to like restaurants, Starbucks or the Seven Mile Bridge which has a 3 mile walk way to a small island. Really love this place and the staff are so friendly and helpful. One bartender actually went and brought me towels for the pool! Great service. Only downfall is that the restaurant is pricey but the food is very good, locally sourced fresh fish!"

Rainbow Bend Resort

10/10 Excellent

"Staff was friendly. Room was great stocked with dishes microwave full size frig. Spacious and had a pull out couch bed that was so helpful. Had a front area with tables and chairs, plus umbrellas. Pool was clean and refreshing. They even had kayaks, paddle boards to use for free. Bikes for free. Even breakfast for free. And not just your continental one, we had eggs, pancakes, bacon,sausage, French toast, It was awesome. I’m so glad I chose them. I felt safe since I travel alone with my teenager that means a lot to me. It’s close to a lot of excursions and beaches."
