My apt. in Lenox Hill is close to East River. Lots of bars and restaurants nearby. 10~15 min walk to F,4,5,6,N,Q,R and 20min walk to Central Park and museums.
I love the neighborhood because it is residential and so convenient to travel to different parts of Manhattan.
It is a 2br apartment and I recently decided to rent out my room, as I am not in NYC most of the time. My housemate, a medical student, is rarely at home and always spends the weekends in his house outside of Manhattan.
