210 Riverside Drive is a stately prewar co-op built in 1909 by architects Schwartz & Gross. This 12-story Renaissance-style building has about 88 units and features a limestone base, ornate plasterwork, and a symmetrical brick façade. The elegant marble lobby—famously seen in You’ve Got Mail—includes coffered ceilings and original Tiffany-style stained glass. A manned elevator with its original 1910 cab adds to the charm. Apartments range from studios to three bedrooms, with high ceilings, spacious layouts, arched doorways, and picture frame moldings.
