Book a Grassy Key Cottage

"The room was very clean. The staff was friendly and helpful. "

"We stayed at Kingsail 4 nights and were very pleased. It’s a very well maintained mote from the 1950’s (probably). Brings back memories of vacation as a child in the 70’s The beds were comfortable and the pool was clean. The location was perfect and breakfast was easy as there is a diner right across the street. When we return to Marathon we will definitely check for a vacancy here. If you’re looking for luxury look elsewhere but if a great low budget place is your desire?Don’t fret just book it. "

"Beautiful!! Gorgeous at night!"

"Quite room and very comfortable"

"Beautiful resort. Such warm touch being greeted with champagne and a reusable water bottle. The room was very spacious and decorative beautifully. The Molton Brown products in the bayhrooom were top of the line and the view from our balcony was incredible "

"Great location to visit Bahia Honda and Key West. We were 3 adults so thankfully we had nice weather to use table/chairs on deck otherwise to eat inside would have been tight. Couch was narrow. TV options was limited-we brought our Box but WiFi did not support using-used hot spot off phone. Really enjoyed our stay and would book again. "

"I am so grateful we choose tranquility bay for our stay. First time to Florida keys and Marathon. Beautiful kept resort. We stayed in the 200S room. The workers were so amazing and nice. They smiled and so polite. Made the stay very nice and felt welcomed. The resort was so well kept. All pools were Beautiful. We had a heated pool right out if our room. With gorgeous landscaping. The private beach was so cool. For us it was a amazing stay, and hope to be back. Thank you so much."
