The current layout offers one formal bedroom and a den, accessible through French doors off the dining alcove. The kitchen includes a separate service entrance leading to a service hallway and egress stairwell.

Both the living room and primary bedroom overlook the beautifully landscaped rear yard and garden, with views of flowering trees and the elegant fa ades of 91st Street single-family townhomes.

Ideally located just moments from Central Park via the East 90th Street Engineers" Gate, the apartment is convenient to top schools, restaurants, museums, shopping, and subway access.
