In the quiet, tree-lined streets of Retiro, this apartment occupies the fourth floor of a well-proportioned early twentieth-century building. The original layout remains intact, offering a sequence of rooms that unfold with a sense of order and proportion. High ceilings and generous windows allow natural light to move freely through the space, while period details—mouldings, door frames and parquet—are present but require restoration to reveal their full character. The presence of a lift ensures accessibility without compromising the building’s historic profile. The apartment is organised around a central corridor that connects the principal areas. The living and dining rooms sit at the front, their volumes defined by the original spatial rhythm. Beyond, the kitchen retains its original layout, with potential for reconfiguration to suit contemporary living. Three bedrooms, each with its own bathroom, offer privacy and functionality. The main suite includes a separate dressing area, while the remaining bathrooms maintain their original tiling and fixtures, awaiting a sensitive renovation. The property is presented in its original state, offering the opportunity to shape a residence that balances heritage and modern comfort within one of Madrid’s most sought-after neighbourhoods.
