Looking for short term rental (ideally furnished, but unfurnished is okay too) for Sept-mid January -NEAQ intern

I (30F) have been accepted to be an intern at the New England aquarium this fall, and haven’t had much luck looking at housing through random rental sites, but if anyone has insight on affordable housing or an available bedroom for a short term lease, I’d love advice or to fill a space in your place!! I’m very respectful of others’ spaces and clean and funny I swear!
