    What's special

    Century old, completely renovated house, in what is considered to be the best part of Key West Old Town. Moments from Southernmost Beach and Point, and across the road from the famous Butterfly Museum. Duval Street is literally a few steps away. No need for a taxi all the bars and restaurants along Duval are walking distance. Completely furnished. The house itself has had no expense spared in creating the fantastic historic timepiece with modern flair. Start your day with a coffee on the front porch or second floor balcony and watch Key West wake up. Modern kitchen with everything you will need to cook your local catch. There is even a professional wine cooler to keep your champagne at the right temperature whilst you laze in your private sun-filled pool or you could cook your shrimp and steaks outside on the grill with additional shaded seating for meals under the sun or stars. Two sets of washer dryers provides for the essentials. Location, location, location is where it is at and where you should be. Renter pays cleaning fees and sales and tourism tax in addition to monthly rent.
