Mostly, I will prefer stairs unless it is a dark, urine smelling dungeon...

For me, it's like the opposite of that. Where the stairs are like that, the lift is in general not very different. You'll never see me using a lift, unless it's a clean, shiny one, with an obvious support system in place. I got stuck in the lift of a hotel when I was a kid, and although it didn't take them very long to get me out, it was enough to scare the hell out of me. I used to have nightmares about it.
So stairs it is...
