I remember living in a 2 floor apartment once that didn't have 3 ways... the stairs were right as you walk in the door to the right, so the entryway light covered the bottom floor.. but then once you got upstairs, you had to get to the opposite wall of the hallway to turn on the upstairs light...

I always did think it was annoying having to walk down or up in the dark, or just leave it on [Linked Image]
