We live the Key Colony area for the quiet, cleanliness, and secure area. Everything is well kept and the staff were friendly and helpful. The pool was wonderful and the beach is very nice (yes, there is the seaweed but no one can control this at any beach in the Keys). They did so well keeping the sand clear. The condo was very clean and well equipped. We love the Marathon area since it is mostly half way to Key West and many restaurants in the area to choose from.

If you are reading all these, you are narrowing down your search. Let me help you - this is it! The perfect mix of pool, beach, perfect lodging, and location. We took two 13-year old girls and stayed in Marathon as our center spot. We flew to FL and then we drove down from Miami and got in around 5pm after stopping at the Publix for groceries. Breakfast and lunch at the condo and dinner out each night. The pool was perfect and never busy - lots of chairs, even during spring break time. The beach also had plenty of chairs and umbrellas and lots of room. We fished from shore at the condo and caught several small fish and grunts, also saw rays and other creatures from the water. The condo is perfectly decorated and was great for the 4 of us. Marathon is the perfect center location for stuff to do, the Bahia Honda State Park, food, turtle hospital, and Key West (90 minutes south). We have ZERO complaints or suggestions for the condo itself - just perfect. Check in/out was easy with the key pad. Bring some quarters for laundry but that was very easy to do. Go to Sunset Park at night (VERY short walk). We loved Island Fish Co. and Sparkys (grilled the fish we caught). Stopped at Robbys on the way down which was super fun in Islamorada. Buy a key lime pie or two for your freezer at night. We will return, and will definitely stay here again. Thank you!
