Lime Tree Bay Resort

Lime Tree Bay Resort

10/10 Excellent
"My husband and I had a wonderful stay! Our room had a small private balcony overlooking the pool, and the water - it was very peaceful. The restaurant next door was excellent and laid back - great place to eat after a day out exploring. the pool is zero entry - so can walk in from the side. they have a cute little sitting area downstairs that would be great to sit and play games - and fun hammocks and chairs by the water to sit and read, rest, or lay out in the sun. The resort is located about half way down the Keys - and was a great spot to use as a base to go out and explore during the day. I would stay here again in a heartbeat!"
