Ideally located in the heart of Biarritz’s historic center, in one of the most sought-after districts of the Basque Coast, this exceptional property occupies the 5th floor of a distinguished bourgeois building, constructed in 1928 by architect W. Marcel. Set on the front line, it offers breathtaking sea views from both the living areas and the master suite, revealing a rare panorama over the ocean and Biarritz's iconic rooftops. With a surface of approximately 238 sq.m., this rare apartment showcases magnificent volumes, timeless elegance, and preserved period charm. The 48 sq.m. reception room boasts nearly 3.80 meters of ceiling height, original pitch pine flooring, a fireplace, and ornate moldings. Bathed in natural light thanks to its double exposure and through layout, the apartment also includes a separate kitchen, a vast master suite with bathroom and walk-in wardrobe, and generous storage spaces throughout. The residence, with its refined and understated architecture, features only one apartment per upper floor — ensuring privacy and exclusivity. The common areas are well maintained, served by a beautiful stone staircase, main elevator, and a secondary service stairwell. A cellar completes this exceptional offering. Just a few steps from the beach, local markets, and Biarritz’s finest restaurants, this property offers an extraordinary living environment, full of history and prestige, with strong potential for enhancement through modernisation.
