It does seem quite sizable to me, too.

Student apartments in Munich's student housing[1] are 14-16 m^2, each with it's own kitchenette and bathroom. They were built in the 1960s and 70s. Those units are by far the most popular way to live for students there mostly because of the common areas, the student community, the wide range of sports and outdoor facilities and the access to public transportation.
