My boyfriend (phd student) has a spot in his apartment in east cambridge for $875 (or at least that's how much he's paying--not sure if all the rooms in the apartment are the same price). Their roommate just moved out unexpectedly so they need a new person until the end of the lease. If you're interested could you provide more details about yourself and what you are looking for?

(Idk how to prove I'm an actual person and not a scammer, but if you dm me I can provide whatever information you need).

(And I agree with the other commenter that that is a very low budget for the area. My boyfriend's apartment is unusually cheap.)
