Hello! I am a Columbia University grad student. I live in a spacious 1 bedroom in Upper West 109th ST. We live just 1 block from the subway, 1 line, less than 5 mins walk to Central Park and Riverside Park, 24hour drug store, grocery store and deli's. The most important thing about my apt is that it is extremely quite during days and nights! And the whole apt will only be you and your friends. BTW, there are two twin size beds in the room. If you feel okay it can fit four people.
