in digs

British slang. To be living in cheap, rented accommodation usually comprised of a room and shared facilities, frequently with meals provided by the landlady. Similar to a 1940's-era "rooming house" in the States. Inexpensive accommodation for single adults such as college students or actors.

"Can I give you a lift to your house, then?" "Oh, I'm in digs at the moment, as it's just me."
