This rare, extra-wide townhouse quadruplex offers the expansive space and unique privacy of townhouse living on a quintessential Upper West Side townhouse block, around the corner from the Museum of Natural History, Central Park, celebrated shopping and dining, and myriad schools and playgrounds. The charm begins as you ascend your private stoop to the impressive entryway with original double solid oak doors. Enter through your private vestibule and foyer to the generous living room and separate dining area dripping with original detail, including two sets of original pocket doors, two ornate decorative fireplaces with original mantels, double south-facing windows with original shutters, and stunning high ceilings accented by crown and base moldings. The wide central staircase retains its elegant original woodwork, and is complimented by stained glass ornamentation between the parlor level and the second floor. The second floor is configured to accommodate a banquet-sized formal dining room or second living room, as well as the adjacent kitchen, which is outfitted with extensive mahogany cabinetry and high-end appliances. There is also a convenient powder room on this level. The third and fourth floors encompass four large bedrooms, most with decorative or wood-burning fireplaces, as well as a study or fifth bedroom, three full bathrooms, a second powder room, and a large laundry room. The private terrace is accessed through the study and has been fenced to create a serene retreat. All bathrooms have been newly renovated. Pets allowed on a case-by-case basis.
