Kretz Real Estate Barcelona

Alexandra Emilia Collado brings the full weight of one of Europe’s most celebrated luxury property dynasties to Barcelona and the Mediterranean jewel of Sitges. As Black Privé’s Premier Partner across Catalonia, Alexandra operates under the Kretz Real Estate banner — a firm that has redefined prestige real estate through an unmatched combination of sophisticated marketing mastery, exclusive off-market access, and a global reputation forged across France and international markets — and amplified by the landmark Netflix series L’Agence, which has introduced the Kretz name to discerning audiences worldwide.

With intimate knowledge of Sitges’ most coveted addresses, Alexandra navigates this exceptional market with surgical precision — where sun-drenched villas overlook the Mediterranean, modernist architecture meets contemporary refinement, and just forty minutes from Barcelona, an exceptionally sophisticated coastal lifestyle awaits. Specializing in exceptional residences exceeding €3 million, she commands deep expertise across the Garraf coastline’s clifftop estates and Barcelona’s most distinguished prime residential enclaves.

What defines Alexandra as a Premier Partner? A genuinely personal advisory approach underpinned by Kretz’s multi-generational family ethos and global visibility — combining the intimacy of a boutique practice with the reach of a internationally recognized luxury brand. Every client acquisition is handled with discretion and depth, ensuring each residence reflects not only exceptional value, but a profound alignment with lifestyle and long-term vision.
