"This is our third trip to Marathon, and I can’t say enough how awesome this property was. Gorgeous views, beautiful decor, immaculate accommodations, and a super responsive and informative host! We will definitely be back to experience the wonderful sunsets right from the balcony! Thank you for everything, Maylin. "

"Very well appointed, nice beach, well equipped, comfortable beds, extra benefit is the "Sunset Beach" park right next door."

"Came for a week over Christmas after the passing of my father. Muffet and her piece of paradise was exactly what this Daddy’s girl needed. We rented bikes locally and used them to investigate Marathon and even took them to Key West for a day as well. We enjoyed all the local restaurants but the Stuffed Pig was a pleasant surprise for breakfast. We will definitely stay with Muffet again in the future. "

"Loved our stay at Key Colony in this new 3 bed, 3 bath home. We enjoyed walking the local area each day and went to sombrero beach. This home has a beautiful view of the pool and inter coastal way. "

"Overall a great place - so clean and it must have been recently remodeled- so cute. It’s too bad the restaurant / bar near the pool was closed. I loved that there were beach chairs available as well. "

"Need a little get away, this place fit the bill. Nice efficiency type condo only a few steps to a small beach with a beautiful ocean view. Close to many nice restaurants. The weather wasn't perfect but managed a swim in the ocean and used the heated pool. Quiet condo complex. Since we only had a few days, the owner accepted a 5 day stay. Would definitely go again!!"

"This might be the cleanest apartment that I’ve rented. The kitchen is nicely furnished and the furniture and bedding is cozy. It’s a little noisy, but it’s a working marina! Good weekend."

"Great property with great views."

"We cannot recommend this place enough! There were 15 of us staying here and everyone loved it. We cooked large meals in the perfectly appointed kitchen while taking in the exquisite views. The activities available on this property are amazing and we all thoroughly enjoyed them: ping-pong, pickle ball, basketball, putting on the green, swimming, paddle-boarding and fishing to name a few...there's something for everyone. Our boys love to fish and they caught (and released) barracuda, parrot...
