Depressing Zillows: Studio apartment edition

The Back Bay has a few available studios here and there for under $2k a month, including this 400-square-foot cutey with a separate kitchen for $1,700.

• For the trust-funders willing to pay $1,900 for the same neighborhood, here's an economical fourth-floor walkup in a Back Bay brownstone.

Around the same monthly price ($1,850) gets you a top-floor space with high ceilings and a full bathtub right on Charles Street in Beacon Hill.
