We stayed at this resort for a business trip, we didn’t really expect much from it. As soon as we entered, we were in huge shock. This hotel was grand and beautiful, I wouldn’t want to spend my business trip anywhere else. Special thanks to the staff and Neidy for making our trip better.

Over priced for what get /service poor
Reviewed 21 hours ago

The resort itself is very nice. The homes are fairly clean and set up nice for families.

With that said we were disappointed with the service. We stayed for 5 days and for the price we expected top service. Our room that we paid for was not ready at checkin. We waited almost 1.5 hours before we decided to take to
another room so we could settle in and begin vacation.

During our stay we had to basically beg for house keeping to come to just get basic towels. I was surprised that daily if they come they will grab towels n not replace most times. They leave no extra soap or dish rags etc you have to call and ask and then they reply but not happily. On the 4th day they did come in as expected n do a full clean etc but other days don't expect a bed to be made or any extras or towels unless you ask.for what you are paying I expected minimally to get my bed made (not changed) n whatever towels we used replaced along with soaps n basics replaced as needed.

I was also disappointed at having no options at all for breakfast - even just ability to grab fruit or a bagel would have been nice. But we did shop n filled fridge etc so that part is ok just don't expect the option.

Family Vacation
Reviewed 1 day ago

First time staying in the Keys and we were very happy. The resort is perfect. Our beach house was clean, spacious, nicely decorated with a gorgeous view. Located on a beach where the kids can snorkel in shallow water and mom can lay on a beach chair in the water!! Tiki bar with food close by, water sports on the premises and pools for everyone to enjoy. We will be coming back next year!

Weekend getaway
Reviewed 2 days ago

My family came down to visit friends for a couple days, Tranquility is a great place to visit, they offer either town homes or rooms, I chose a room because it was only the kids and I , everything is close enough that the walk out to the beach and tiki bar wasn't too far, the Resort offers plenty of stuff for the kids to do to keep them busy, the kids loved the pool just downstairs from our unit and just steps from the gym. The number one thing that stands out is the customer service from the staff they are amazing. Hope to see them all again soon.
