It comes from Old English 'flett' meaning floor, hall, house and related to 'flat'. Probably because it's flat - all on one level - as opposed to a house which is on more than one level. Unless it's a bungalow, but they aren't stacked up like flats. If it's stacked up but on more than one level, it's a maisonette.
