We drove from Naples and thought we might just check in after the long drive, and then maybe go on to Key West. After seeing the resort, no one wanted to get back in the car. What a beautiful place! We rented a wave runner, enjoyed the tiki bar, and the pool. The cottage we stayed in was gorgeous!! Two... More

Simply perfect. I love that it wasn't a party resort. It was quiet, the staff was exemplary and beyond friendly. It takes a place like Tranquility Resort to understand what true relaxation feels like. The only recommendation is to set up a designated smoking area somewhere on the grounds. It's sort of ridiculous to have to walk out to US1.... More

Before booking our trip to the Florida Keys I looked and looked at different properties in the Keys area. Nothing sparked my interest a whole lot until I came across Tranquility Bay. The pictures on the web site were absolutely BEAUTIFUL!! Typically I figure they pick the best of the best pictures and it is not always like that once... More

For the Keys, this is upscale, but very lacking on resort feelings. Seems the units are mostly privately owned and rented out for the night, week, etc. and property is therefore run by a management company, which results in less than super friendly and professional & and sufficiently staffed front desk and outdoor drinking and lunch.

Beautifully done resort, both the interiors and exteriors were nicely designed. My one complaint on this front (and it is a big one) is the extreme lack of privacy. All the decks are right on top of each other and something, anything - even just roll down bamboo curtains - would be preferable to the current exposed porches! Two other... More

First time at Tranquility Bay, and it is a really great resort. We stayed in one of the regular rooms #206 and even though it is on the second floor and there are only stairs it was great - there is a handicap lift to the second floor rooms I noted. The room was not just a regular hotel room... More

This resort was perfect for our couples getaway, we were in the beachfront room (2 bedrooms) last room on the side. It was peaceful and quiet. We traveled with another couple. The rentals were conveniently located on site for kayaks and jet skis.

This was the second time we stayed at Tranquility Bay. We rented a 2 bedroom waterview house. I can not say enough about this place! The houses are beautiful and so is the property! If you want to just lounge in the pool or beach all day... this is the place, if you want to do watersports onsite it's all... More

Stayed here Fall 2013 and it was incredible. The grounds were beautiful and well maintained. Loved having an adults only pool (the larger pool is a family pool). Our room was ocean front and the view was incredible, from coffee in the early morning to a glass of wine at night it was perfect. Would stay here again and again!

This probably would have gotten five stars from me, but since I had been at Cheeca the night before in Islamadora, I can't help but compare them. I do like that this one was located on the bay side which makes it a better location for the beautiful sunsets. I did love the way they decorated their rooms since the... More
