Perfectly positioned at the corner of East 71st Street and Fifth Avenue, 900 Fifth Avenue is one of the most distinguished post war co-ops on the Upper East Side. Directly across from Central Park and the historic Frick Collection Museum and Library, this coveted address offers a front-row seat to some of Manhattan's most iconic architecture and scenery.   With only three residences per floor, the building provides exceptional privacy. The C-line is especially desirable-offering a private elevator landing and open views over the Frick gardens, Central Park, and the Midtown skyline.   Residence 10C is a recently renovated expansive Classic Six, approximately 2,000 square feet, combining timeless elegance with gracious scale. The home features a grand entry gallery, formal dining room, and spacious living room with beautiful southern light. Two large bedrooms with en-suite baths, a guest powder room, galley kitchen, staff room with bath, and separate service entrance complete the thoughtful layout.   The living room and primary bedroom face southwest and overlook the Frick gardens and Central Park, capturing an ever-changing panorama of the city-from golden sunsets over the trees to the twinkling lights of Midtown. A rare opportunity to own a Central Park-facing home on Fifth Avenue, Apartment 10C offers the perfect blend of historic charm, architectural integrity, and modern comfort in one of New York's most timeless neighborhoods.   Built as a luxury cooperative, 900 Fifth Avenue allows 50% financing and welcomes international and pied-à-terre buyers.  Pets allowed. The lobby, redesigned by AD100 designer Juan Montoya, features exotic woods, lacquer finishes, and polished stone, setting a refined tone from the moment you arrive.   Residents enjoy a 24-hour attended lobby, fitness center, private storage, two landscaped roof terraces with panoramic 360 city views, a bike room, and an on-site garage.  Monthly maintenance includes utilities, and there is a 2% flip tax paid by the purchaser.
