We were on our honeymoon. We had a very nice relaxing trip. The pool was clean, the view was great, and the service excellent. The location was ideal. It was a short drive to everything we wanted to do. All the lady’s at the front desk were so helpful and gave us must see spots. But we were able to come back to a beautiful and calm room. We stayed on the top floor and had a great view of the ocean.

The front desk staff was so helpful with my early check in. I also got to meet the main owner of the resort (Wilma) who was very welcoming with her purring and head bumps🐱🐈, she definitely made my stay 100 times better! The rooms were spacious, clean, and comfortable with a beautiful view. I’ll be returning the next time I visit the Florida keys!

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.

Did not meet expectations

The overall resort is clean. The beds were uncomfortable, too soft. There is a beach, however the beach is less than desirable. The pictures on their website and hotels.com are not what we experienced. There were tracks from equipment on the beach. There are limited beach chairs on the beach and surrounding the adult pool. The kayaks we wanted to use were broken and had a limited supply of other equipment. The hours for use of the activities equipment are limited, stopping at 5pm. No hours posted for the pool, however we’re told not to be used after sunset despite being an adults only pool. The tiki bar closes at 6, however there are other places for food and drink, but not appropriate to wear pool clothing to. The sunrise was beautiful both mornings we were there.

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.
