Grassy Key Hotel Reviews

Fairfield Inn & Suites by Marriott Marathon Florida Keys

5/5 Excellent

"The property and the employees ( Jahneil ) were excellent. My problem is I booked through Expedia. And it took such a long time for my information to be sent to the hotel front desk. The young lady that took care of us is an exception and a service to the facility. The parking was very tight and getting around. The parking lot was very busy, other than that we had a great stay."
