Hard to find the main office to check in. Local store limited on supplies. Older property which wasn’t bad. Not much beach. Room was big and nice. No coffee supplies so make sure you bring your own.

Beautiful location and plenty of thought put in to comfort. Only stayed one night but wished I'd booked more.

The property was nice, but there were some disappointments: 1. Someone should be at the front desk at night when something is needed. 2. Restaurant was extremely overpriced and not very good.

Great family vaca! What a great stay we had! Our first time in the keys and it was fantastic! We booked 2 nights initially but after spending time at the tiki bar with Jeff while waiting for our room and watching the kite surfers, we booked a 3rd night. The front desk staff was very accommodating and kind and Joe the tiki bar bartender made great tropical drinks and played incredible music. We are already plotting our next vacation here!

Family owned resort. The staff was fantastic. The place was beautiful. The beach was gorgeous. Husband and I came down for the week on a getaway. He scuba dived three days and I laid on the beach which felt like my own little island. The room was very clean and comfortable. Will definitely be back again.

What a cozy atmosphere! The rooms were decorated beautifully, the roof top bar and hangout was awesome. The staff there were fun and friendly, and the musicians singing were amazing. Very entertaining! Restaurants close by, but the roof top had appetizers that are delicious. Megan and Marvin were so nice as our bartenders. We can’t wait to visit again.

Everything in and around the property was really nice the only thing I didn’t like was the beds in the rooms were very loud and uncomfortable. We had two rooms booked and in both of the rooms it was the same issue.

Property right on the water. Most everything was great. It was nasty out when we arrived and we were told to come back another day for a tour of the property. Went back and asked about tour but office person Morgan didnt seem to care even though she is the one that told us to come back. All other office personnel were great.
