Hotel Details

Location

One block from Duval Street and a short walk to the Ernest Hemingway Home, this quiet residential location puts most of Key West's attractions within easy reach on foot or by bike.
The property sits on Truman Avenue, a quiet residential street that is a few minutes' walk from the vibrant Duval Street area. The Ernest Hemingway Home and Museum is an 8-minute walk, South Beach is less than 1 km away, and the Southernmost Point is a 13-minute stroll. Key West International Airport is 3 km from the hotel. The neighbourhood is safe and walkable; a hop-on-hop-off bus stop is nearby, and the property offers complimentary bikes for exploring. The location allows for easy access to waterfront dining and nightlife while being far enough to avoid the noise of the main strip. Parking on-site is limited to 4 vehicles, but free street parking is available, and EV chargers are on the premises.

Accommodation

Individually decorated rooms with private bathrooms, air conditioning, and garden views-each opening onto the historic property's lush grounds.
Each room includes air conditioning (some with two units for reliable cooling), a private bathroom with shower, free toiletries, bathrobes, and a hairdryer. Rooms feature garden views, private entrances, and some offer patios, terraces, or wraparound balconies with outdoor seating. The spacious Treetop Suite and Caribbean Queen rooms provide extra space and natural light, while the Garden Room has direct ground-level access to the gardens and plunge pool. Room amenities include a work desk, wardrobe, ironing facilities, and a sitting area. The historic wooden building (built 1904) may have slight quirks typical of older properties. A communal TV and shared mini-fridge are available in the main house. Wine or champagne is offered upon arrival.

Dining

A complimentary hot breakfast is made to order each morning and served in the garden courtyard, with a daily rotating menu that includes fresh fruit.
Breakfast is included in the stay and consists of a single hot entrée each morning, rotating through 9 different dishes, served in the garden patio setting with a fountain. Fresh fruit and made-to-order options are available. The property also offers a daily happy hour with wine and cheese, plus 24/7 access to coffee, tea, soft drinks, bottled water, and light snacks. Nearby dining within a 5-minute walk includes Bobby's Monkey Bar, El Siboney Restaurant, and Little Pearl. The full kitchen and dining area in the main house are available for use.

Wellness and Leisure

A heated plunge pool with jets and a sun terrace, set within a lush garden with shaded seating and a fountain.
The property features a small, heated outdoor pool with jets (often described as a jacuzzi-sized plunge pool) that is open all year round. Sun loungers and beach umbrellas are provided. The landscaped garden includes a hot tub, fountain, and multiple quiet seating areas, ideal for reading or relaxation. Massages can be arranged in the garden cabana with advance booking. The adults-only policy ensures a quiet atmosphere throughout. Complimentary beach towels, coolers, and sunscreen are provided for trips to South Beach or other nearby waterfront spots.
