An exclusive 203 m² (built area) residence, fully renovated and located in an elegant, historic 1900s building with an elevator, in the heart of the "Quadrat d'Or"—one of Barcelona’s most prestigious and sought-after residential areas. Situated on the third floor, this magnificent property blends the charm of Barcelona’s Modernist architecture with a meticulous, high-end renovation. Original architectural features have been preserved, lending the home a unique character and personality—notably the traditional Catalan vaulted ceilings (*volta catalana*) and exposed brick walls. The living area is designed as a spacious, light-filled open-plan space, integrating a living room, dining area, and a spectacular, fully equipped designer kitchen, anchored by a large central island and a functional breakfast/work area. It offers an elegant, welcoming atmosphere, perfect for both daily life and social gatherings. The residence features four generous double bedrooms and three full bathrooms, including an impressive primary suite with a private en-suite bathroom. The layout has been carefully planned to maximize comfort, privacy, and functionality throughout. Its dual orientation ensures an abundance of natural light all day long. On the side facing Carrer de Roger de Llúria, the property boasts two pleasant east-facing balconies, while the rear façade features a sunny, west-facing gallery. Accessible directly from two of the bedrooms—including the primary suite—this space offers a tranquil, privileged retreat overlooking the interior courtyards of the Eixample district. As an added benefit, the property includes a practical 13 m² private storage room located on the building's top floor. Situated at one of the finest addresses in the Eixample Dreta (Right Eixample) neighborhood—just steps away from Passeig de Gràcia, Passeig de Sant Joan, and Plaça Catalunya—the residence enjoys excellent connectivity to the rest of the city, along with easy access to a wide array of shops, restaurants, services, and cultural amenities.
