Description
Located at 521 United Street, the Southernmost Inn was originally built in the 1800s as a Francisco Marrero cigar factory. With much of the old cigar factory features restored, the award-winning transformation allowed the old Key West designs to live on throughout a modern-day establishment. The Southernmost Inn offers 38 newly renovated rooms featuring modern interiors with a classic neo-colonial design. All guestrooms feature en-suite bathrooms, flat screen TVs, and colonial wooden blinds. The Boutique also boasts a gorgeous outdoor common area with lush gardens, two pools, one jacuzzi, a bar (currently closed), and a relaxing dining area.
