In the heart of Chamberí, on Calle Trafalgar, this 1959 building anchors one of Madrid's most characterful neighbourhoods—a district defined by tree-lined streets, independent galleries, and a lived-in elegance that resists trend. The apartment occupies a generous footprint within this period structure, accessed by lift, and retains the proportions and light that define mid-century Madrid residential architecture. The home unfolds across multiple rooms with a clarity of purpose. The principal living spaces benefit from natural light and high ceilings characteristic of the era, while the layout accommodates four bedrooms and three bathrooms without compression. A terrace extends the interior outward, offering a rare outdoor space in this densely woven neighbourhood. The apartment has been renewed to contemporary standards while preserving the spatial generosity and material warmth of its original conception.
