Lime Tree Bay Resort

Lime Tree Bay Resort

10/10 Excellent
"What a gem! This was a cozy place to relax and stay for several days in the keys, very reasonably priced. I had a great view of the bay and saw beautiful sunsets.there is a very nice well maintained pool. Parking was free, and they offer great amenities. I enjoyed the restaurant/bar next door too, they have great food and cool island vibe. This place isn't exclusively for adults, but most of the patrons were and I liked that. It's probably not the most exciting place for kids."

"The facility is beautiful, clean and well maintained. The staff are amazing, warm, friendly and helpful. The resort fee gives you access to rent various things which helped us to have a nice beach day at a beach recommended by the staff. The infinity pool is beautiful and located near the bar, which is nice! There are actually multiple pools on property. We loved our stay and will be back!"
