Reviews for Tranquility Bay Beach House Resort

TripAdvisor Traveler Review Rating Reviewed 2 days ago

I’m happy I chose this resort to spend a weekend with my family. As the name states “tranquility” was all over. Not a loud noise, except for my toddler and 7 month old…. Sorry guys lol. But, everything was excellent except the pack and play. I would suggest adding a mattress because putting a baby to sleep in a hard surface is just sad. I tried putting folded blankets I brought from home, however, it was still hard. Placed the baby to sleep me with me the following night and I just didn’t rest. Aside from this small complaint, everything else was clean, kitchen was fully equipped with pts and pans, salt and pepper, glassware, cutlery, cutting boards, microwave, kettle, oven, fridge, dishwasher, washer and dryer. We would definitely return.

Family Vacation 2025

TripAdvisor Traveler Review Rating Reviewed 3 days ago

Tranquility Bay was so beautiful. The villa we stayed in was perfect. The grounds were captivating and something out of a picture book. The bed in the Master bedroom was so comfortable and the sheets and pillows were so soft. The view from our room was breathtaking. The other rooms were nice. The couch in the living room was a pullout couch, but ours was old and did not work. I think if that was updated to a more comfortable functional pull out the sleeping arrangements would’ve been a little bit better since we traveled with our adult children. The twin beds in the one room we’re just a little bit small for two adult children. Everyone at the resort was always trying to make sure we were taken care of and had everything we needed. If we didn’t have something we could text and they would bring it over asap. Super great service! Definitely would stay there again!

TripAdvisor Traveler Review Rating Reviewed 4 days ago

Perfect location for the keys Quiet side of Marathon and minimum sargassum when we visited Waterfront villas are fabulous-spacious, well maintained. Washing machine and dryer. 3 toilets. 87 had a great sunset view. All amenities provided for Great staff Large lagoon style pool. Cove sandy beach. Butterfly cafe fine dining. Large portions Tips: Coast to coast pizza fantastic. Deliver to the resort Turtle hospital must visit! Resort provides complimentary bikes for 7 mile bridge Simple groceries available across the road. ID needed for alcohol even if older Agree bug spray needed Better location and villa accommodation than Isla Bella (chose this 3 bedroom villa over 2 bedroom linked rooms) Key West an hour away Visit Florida key outlet for best discounts

Yoga for all levels

TripAdvisor Traveler Review Rating Reviewed 6 days ago

I attended Lynne’s yoga class while at Tranquility Bay. She was careful to accommodate all levels of yoga experience into her stretches and poses. I always need the reminders of when to inhale and exhale my breath, so this was perfect.
