The building is located in the aristocratic area par excellence of Madrid, a reflection of nearly a century of history, and has been home to several Embassies. It is situated a few steps from Almagro, Serrano, and the U.S. Embassy. Built in 1928 by the architect Severiano Sánchez Ballesta, it maintains the classic elegance of the facade with a marked French influence and has been completely refurbished inside. This duplex penthouse of 390 m2 has 4 en-suite bedrooms plus a guest toilet and a service apartment with an independent entrance, something completely unique, customizable in layout and quality to meet the demands of our clients. Its ceilings exceed 3 meters in height, and its open spaces, generous galleries, and kitchen equipped with the latest technology appliances create an elegant and contemporary experience. Balanced and sophisticated spaces have been created, offering the most delicate details in the moldings, contemporary finishes, and noble materials from the most prestigious brands. Castellana Residences offers residents an elegant variety of state-of-the-art spaces for exercising, relaxing, or entertaining, inspired by exclusive social and wellness clubs. All residences provide a sensational panoramic view from their balconies towards the urban landscape and the sky of Madrid. The majestic balconies harmoniously connect the interior of the dwelling with the Paseo de la Castellana, bathing each space in natural light. Castellana 45 enjoys the best of both worlds: living in an exclusive residential area and being in the center of a cosmopolitan and vibrant capital like Madrid, with countless leisure, culture, and entertainment options. Excellent communication with the Adolfo Suarez airport and several metro and bus lines.
