"Beautiful outdoor patio, amazing pool, and a very well air conditioned house. We had a great week here, only thing we wished was different was the jacuzzi connected to the pool was the same temperature as the pool, other than that, fantastic host and property. "

"Everything in the listing was completely accurate. Halfway point in the Keys. The home was very clean. Air Conditioning was spot on. We used the pool/hottub a lot. Surprised how much we used the hot tub as almost every day it was clear and hot. Although it didn’t bother us, the home is located in the direct path of a variety of planes jets and helicopters landing at Airport nearby. Noise was quite loud and may scare some dogs. Our Morkie had no issues. Definitely would rent property...

"My family (10 of us all together) stayed at this beautiful property and could not have been more pleased! It was spacious enough for all of us and close to all the things we wanted to do! Beth was super responsive anytime we reached out to her! The only thing I would note is that the house is in the DIRECT landing path for the airport down the road. It was a little startling when some of the jets were flying in. This is nothing against the house itself, just something to be aware of.We hope to...

"Great week in the Keys! This property has amazing outdoor space! Great fishing off the dock, easy access to Sisters Creek and the Atlantic. The pool area is perfect and well kept. Very quiet and private neighborhood and close to everything, restaurants, grocery store, and beach. The house is well equipped and has COLD A/C, it is a bit dated but suited our family and friends just fine. We are outside people and just need a place to shower and recoup for the next day.. We would definitely stay...

"This place was nice and had some updates. The biggest thing for us is cleanliness. The housekeeper on the property needs to do a thorough job vacuuming and a least wash the floor every now and then. There were LONG dark hairs all over the place. That’s what prompted us to vacuum and the floor “looked” clean but was dirty. We washed the area we were using. We only used the main bedroom and the bed was very comfortable. The bathroom had been updated in recent years and was very roomy. The...
