Room was nice especially considering the age of the house. Staff was super friendly and helpful. Lobster pizza at the attached bar was awesome! On the quiet end of Duval street so it was very relaxing when we wanted it to be, but we would walk to the other end to explore, drink, eat etc.

Our stay at The Mansion on the Sea/Southernmost House was absolutely exceptional. From the moment we arrived, everything exceeded our expectations. The ocean views are simply breathtaking — waking up and seeing the water right outside felt like a dream. The location couldn’t be better: peaceful and scenic, yet close enough to enjoy everything Key West has to offer. The property itself is beautifully maintained. Every detail reflects care and pride of ownership. The grounds, rooms, and common areas were spotless, elegant, and incredibly comfortable. What truly set this stay apart, though, was the staff. They were warm, welcoming, attentive, and genuinely committed to making sure every part of our visit was perfect. Their hospitality made us feel valued and completely at home. If you’re looking for an unforgettable Key West experience with stunning views, prime location, and top-tier service, The Mansion/Southernmost House is it. We can’t wait to return!
