Boris L - $800/month

I am a musician, looking to move in at a room by a month-to-month basis in NYC for preferably $800 or less a month budget. I plan to move in with a friend of mine, so it would be great if there is a room with a vacancy of at least two people. I would prefer to share a room with a few other people as well, preferably young professionals in their 20s and 30s. I am 29 years old. If an apartment can fit an upright piano, that would be a bonus.

Thanks for all the heads up!
Boris
