Castellana Residences brings together a selective collection of renovated apartments along one of Madrid's most prestigious addresses. This four-bedroom residence occupies a carefully restored building whose protected façade speaks to its architectural heritage, while the interior spaces have been thoughtfully reimagined for contemporary living. The apartment unfolds across 474 m² of interior space, anchored by a 95 m² terrace that frames views across the city. The layout moves from the entry through generous living and dining areas toward the kitchen, designed as an open extension of the social spaces. Four bedrooms and five bathrooms provide flexibility and comfort, with natural light entering from multiple exposures. Climate control, smart home systems and security infrastructure operate discreetly throughout.
