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. 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.
