— INVESTMENT OPPORTUNITY — We present this charming 3-bedroom duplex apartment located in the heart of the historic town of Sintra. Its location is truly privileged: just a 2-minute walk from the train station, 5 minutes from the historic center with its palaces and gardens, and only 1 minute from ISCTE University. Perfect for students, families, or investors looking for a high-return property in a prime area. The apartment is spread over two floors. The main floor features two spacious bedrooms, a bright living room, a fully equipped kitchen, and a bathroom. This level boasts high ceilings and wooden flooring, offering both charm and elegance. The attic has been converted into a large additional bedroom with sloped ceilings, another bathroom, and generous storage space—making the apartment ideal for both personal living or tourism accommodation.
