Located in a listed 1913 building in the sought-after Joncs Marins residential area of Le Perreux-sur-Marne, this bright duplex apartment of 98.9 sqm total floor area (61.9 sqm under Carrez law) occupies the second and top floor of a well-maintained walk-up building. Close to public transport, schools, and local shops, it offers an ideal living environment combining peace and convenience. Fully renovated with care, the apartment blends modern comfort with preserved period character. The first level includes an entrance hall leading to a spacious double living room featuring a bow window and a Prussian stove—an adaptable space allowing the creation of an additional bedroom—as well as one bedroom, a separate kitchen, and a shower room with WC. Upstairs, a bedroom with en-suite bathroom and a study under the eaves—easily convertible into a bedroom—complete this unique and functional layout. Modern upgrades such as internal insulation, recent boiler, and double-glazed windows complement the preserved original features: decorative moldings, hardwood flooring, and charming sloped ceilings bathed in natural light. A rare property, both elegant and updated, located in one of Val-de-Marne’s most desirable and tranquil neighborhoods.
