Studios on quiet, tree-lined blocks in the Upper East Side don't come up often at this price point. This one faces the rear of the building, overlooking the co-op's shared garden — which means it's calm, it's green, and it doesn't face the street. Inside: separate kitchen, hardwood floors, high ceilings, good closet storage, through-wall AC, and a windowed bathroom. The apartment is move-in ready, and a new owner could easily make it their own with a fresh coat of paint, refinished floors, or an updated kitchen. 215 East 89th is a well-maintained cooperative with laundry, bike storage, and garden access. The sublet policy is generous — permitted after two years of ownership, with no time limit. No pets or pied-à-terres. The 4/5/6 and Q trains are nearby, along with the M86-SBS crosstown, Whole Foods, Fairway, Central Park, and the 92nd Street Y. Images are virtually staged.
