>>211999514my russian gf owns a flat in komunałka, she rents it to some student girl
it's a previously large apartment in an old german building that got parceled into 6 "flats" (consisting of 1 room) with shared toilet, bathroom and kitchen
mostly old and poor people live in these
renovating anything in shared spaces is almost impossible as it requires consensus of all the people living there, so you basically need to convince some half-dead boomers and hopeless alcoholics that renovation is needed, everyone needs to sign a notary document
