Modern apt in the heart of NYC and close to subway. You will have your own private room. If I'm around and free, I can probably get you into most museums in town for free.
There are a ton of restaurants and bars in the neighborhood. If shopping/window shopping is on your list of to-dos, Fifth Ave is not too far.
The apt is close to many trains: 4/5/6/S/7/E/M. Grand Central and the UN are both a short walk away. If you want to take a cab, you are not too far from most places of interests in Manhattan.
