Extremely rare opportunity to purchase the penthouse unit of one of the only classical, three story buildings on Russian Hill's iconic flat block of Chestnut Street. The living room views are unobstructed with Alcatraz and the Bay front and center. To the left is the Golden Gate Bridge. The Penthouse unit has never before been sold and has been meticulously maintained with elegant details throughout the unit, from the spacious living room with working a fireplace, traditional dining room adorned with English sconces and crystal chandelier, to the master bedroom with its hand blocked Zuber wallpaper that was part of a limited series commissioned by the Metropolitan Museum of New York. The spacious floor plan includes the elegant living room featuring expansive bay views, formal dining room, chef's kitchen with Viking Range and Bosch appliances, 3 en-suite bedrooms, in unit w/d, powder room and generous storage throughout. One large deeded parking space completes the perfect full time residence or city pied-a-terre.
