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.

We had a wonderful time at The Mansion. The staff and facilities were great and we will stay here again when we visit Key West. We especially appreciated the breakfast and the staff’s timeliness on a small issue we had in the room. Thank you everyone!

This property is full of history and character. The staff helpful and friendly. Not a problem for us but there is no lift/elevator, they offered to take our bags to our room which was on the top floor (UK 2nd/US 3rd). Self serve breakfast provided which was great - plenty of options; fresh fruit, yoghurts, bagels, juice, cereal, pastries. Chilled bottled water available all day. Is at the end of busy Duval St, so during the daytime is quite busy with tourists visiting the cafe adjacent to the residents only pool, but at night was quiet. The hotel was also a participating venue in the Songwriters Festival, so live country music and tourists were present in the afternoon!
