The main level features a spacious living room, formal dining room, and a private primary suite with direct access to the lush poolside setting and outdoor dining pavilion. The chef's kitchen is designed for both everyday living and entertaining, boasting stone and copper countertops, professional-grade stainless steel appliances, and seamless flow to a pergola-covered outdoor dining, perfect for hosting memorable gatherings. Upstairs, two generously sized bedrooms share a stunning, renovated bathroom with refined finishes, offering comfort and privacy for family or guests. The outdoor spaces create a true private oasis, complete with a large swimming pool, sun patio, built-in wet bar, laundry room, and additional storage. A separate one-bedroom guest cottage with its own bathroom provides ideal accommodations for visitors or extended stays. Gated off-street parking adds convenience and privacy, an exceptional feature in Old Town.

    "I've lived here for 2 years and enjoy the walkability to local theatres and restaurants. There's a strong homeless contingency that detracts from the seaport. But you can't blame them for wanting to be in paradise."
