Fairfield Inn & Suites by Marriott Marathon Florida Keys

Fairfield Inn & Suites by Marriott Marathon Florida Keys

10/10 Excellent
""We had a very pleasant stay at Fairfield Inn & Suites Marathon. The room was clean, comfortable, and well maintained. The staff was friendly and welcoming throughout our stay. Breakfast offered a good variety and was convenient before heading out for the day. The pool area was relaxing, and the location was great for exploring Marathon and the Florida Keys. The only minor downside was that the hotel could get a bit busy during peak hours, but overall it was a great experience. I would definitely stay here again.""
