We wanted to have a few days away to unplug and relax. We spent most of the days in the great pool where we could be in the pool and gaze out at the water. With the palm tree providing filtered sun in the mid afternoon, it was a place I could have stayed for days. The rooms were great and clean. The staff was very pleasant, helpful and accommodating.

Really loved this hotel. The room was quaint but beautiful and well maintained. Bed was comfortable and everything worked as expected. The staff were very nice and easy to deal with. Also loved the location. Right at the very southernmost end of Duval Street, it was easy to get everywhere we went whether by Uber, golf cart, pedicab or walking. Would stay here again in a heartbeat. Thank you.

Rich in history.
An absolutely amazing stay. The hotel manager greeted us by name and took care of every detail, including getting us a table at their amazing cafe. We were greeted every morning, the breakfast and coffee were amazing and the staff was super helpful. The history, culture, and vibe of the hotel made it a truly unique and amazing experience. I would recommend it to everyone and we will definitely be back.

We found the customer service at The Mansion on the Sea to be outstanding. They pay attention to detail and offer assistance when needed. We met the owner while there, and that is something you almost never see at corporately run resorts. We would highly recommend and will return again.

It was our first time in Key West so we were not sure we’re to stay. We pick the Mansion by the sea from the beautiful pictures. We had a great time and the grounds were beautiful. The staff was amazing and the pool was amazing.
