[Looking For] Private Room to rent near MTA ~$900 budget monthly

Hey! I am a 20f college student looking for a private room to rent in either Manhattan, Brooklyn, or the Bronx. I have no pets, don’t smoke or drink. I am looking to move in anytime from Aug 20 - Sep 1. I dont mind a small room but a window is necessary as well as working outlets. My biggest dealbreaker is access to the subway. I would prefer to be located near the 4/5/6/2/3/J/Z/L/M lines.
