Located in the seaside area of Katafygi, within the wider Anavyssos region of the Athens Riviera, this property enjoys a privileged position just a short walking distance from the beach and the local seaside chapel. The setting combines relaxed coastal living with open sea views in a quiet residential environment. The property is a true duplex residence with two fully independent homes, each with its own private entrance, offering a total built area of 255 sq.m. on a 640 sq.m. corner plot. Each level operates as a self-contained residence, making it ideal for multi-generational living, guest accommodation, or investment use. Both residences feature open-plan kitchen and living areas, storage space, fireplaces, and access to two private parking spaces within the plot. The ground-floor residence 145 sq.m., offers a practical family layout with 3 bedrooms, 2 bathrooms, and 1 WC. It enjoys direct access to a private landscaped garden with sea views and a seamless connection to the surrounding outdoor space. The first-floor residence 110 sq.m. includes 2 bedrooms, both with en-suite bathrooms, along with an open-plan kitchen and lounge area. It benefits from large balconies with panoramic sea views, abundant natural light, and a western orientation that enhances sunset views. The first-floor level features tiled flooring, while the ground-floor residence has a different flooring finish, adding character and distinction between the two homes. The property is designed for comfort and security, featuring security doors, aluminum frames, and alarm systems throughout. Both residences are bright, airy, and oriented to maximize sea views and natural light. Built in 2000 and fully renovated in 2019, the residence is in excellent condition, combining solid construction with modern upgrades and practical layouts. The setting is quiet and residential, with direct walking access to the beach enhancing the overall seaside lifestyle. Located within the city plan and served by asphalt road access, the property is well connected to Anavyssos, Palaia Fokaia, Lavrio, and Cape Sounio, while maintaining a peaceful coastal character. A rare opportunity to acquire a spacious seaside duplex residence in Katafygi, where both independent homes enjoy sea views—one through a private garden setting and the other through expansive panoramic balconies.
