Properties like this are one of a kind. Either you embrace this or you don't. Old houses will have creaky stairs and require constant maintenance. Our house that we live in is decades older than the Southernmost House so we are familiar with these things.
We had a 3rd floor suite that included the turret. Sunrises were spectacular from the turret.
Being on the top floor the WIFI was a little weak but usable. Water pressure was also a little weak but livable.
We loved the room.
The back pool and deck area is great. It never gets crowded and is very relaxing to sit out there. Restaurant and bar is just steps away.
The funny thing about staying here versus other Key West properties is you can stay within a block or two of the house and have everything. We found ourselves wandering out less often than in past Key West trips.
This property is truly special and one of a kind.
