This is the second bedroom of my apartment. It's just one block away from the 110 St subway stop (1 train), and a short walk from Columbia University. You'll get full apartment use, including the kitchen and the common area (both shown in photos). The room has a window AC unit and can if needed accommodate two guests (full size bed). The apartment is on the 4th floor of a brownstone walkup.
If you have any questions of course don't hesitate to ask!
