I've generally found that the order of the names on the doorbell list roughly matches your floor. So if you're on the 2nd floor, right side from the stairs, your doorbell is second from the bottom, on the right side. Obviously, there's no standard nor convention, but Hausmeisters seem to find it convenient, and I like it when I can do that when visiting a friend for the first time. Of course there are, however, apartments whose Haustür (the door to the apartment building) leads to several different buildings or staircases. In that case, good luck ever finding that person even if they want you to come visit.
