Great location. Loved the history of this Southernmost House. I did a lot of investigating for an historical accommodation in Key West, this matched my checklist perfectly! History, architecture, superior accommodations, great oceanfront view and delightful heated pool. Breakfast was top notch and the staff is marvelous and very accommodating.
