"My husband and I spent the week at this wonderful VRBO in Marathon. It was a great location and easy to take fay trips to the other Keys. Great communication from Michael. Thanks to his help we were able to watch the Key Colony Holiday Boat Parade in the neighborhood"

The Tides Unit at Emerald Flats

10.0 out of 10, Exceptional, (1)
"This was the perfect stay from ease of check in to fast check out! We really enjoyed marathon key and it is a beautiful and easy drive to other Keys. House is very well stocked and clean! Our kids enjoyed a dip in the pool on our off days and we enjoyed the short drive to Sombrero beach and Bahia Honda Key state park. Lucia was a great host, available for anything we needed, but honestly we didn’t need her!"

"The condo was great, lots of windows, comfortable furniture and a well-stocked kitchen area (implements, not condiments). The view was amazing out to the Gulf and down the cut. We definitely plan on coming back."
