Even among the many pre-war condo listings on the Upper West Side, The Apthorp stands out for its impressive pedigree. The building, at 390 West End Avenue, was built by William Waldorf Astor in 1908, and was modeled after the famed Pitti Palace in Florence, Italy. That doesn't exactly bespeak modesty, but a recent restoration has highlighted just how grand (and occasionally grandiose) Astor's vision for The Apthorp actually was. The building itself is stunning, and one of the most impressive pre-war condos in Manhattan. But while The Apthorp is a great building, it has yet to take off as a star NYC condo listing because of the ongoing tussle over that ambitious restoration.
