A Classic pre-war layout at one of the Upper East Side's most coveted addresses: four large bedrooms, a library, large great room, eat-in kitchen, two wood-burning fireplaces, and south-facing tree-top views across 3,000 square feet. Arrive off a semi-private elevator landing into a 14' x 14' entrance gallery with real symmetry and room for coats, bags, and everything that comes with a full life. From there, the double living room opens up, 37 X 20 feet, five south-facing windows, and two wood-burning fireplaces anchoring either end. It's the kind of room that works equally well for a dinner party of forty or a quiet Sunday morning. The kitchen was renovated with care: white custom cabinetry, Caesarstone countertops, wood floors, and a banquette and table with plenty of room. The appliances are Sub-Zero, Thermador, and Viking. There's a windowed bathroom off the kitchen, and the whole space gets great light. The split-bedroom layout gives everyone their own wing of the apartment. The primary suite faces south, has serious closet space, and a windowed marble bathroom with an oversized shower. The three bedrooms on the eastern wing are well-proportioned and comfortable, one has an en-suite bath, making them genuinely usable for family or guests. Through-the-wall AC is located throughout the apartment. Hardwood floors run throughout. Closets are everywhere. The architectural details are fantastic. The ceilings are high. 340 East 72nd Street is a 1930 white-glove co-op with just 33 residences. The building has a full-time doorman, a renovated gym, a landscaped garden, laundry, bike storage, and private storage cages. The building even supplies the firewood. Also included: a staff room that is used as an office with a charming view overlooking the garden (maintenance $598.47), plus a large private storage cage. Pets welcome. 50% financing allowed. 2% flip tax payable by buyer.
