The stairs I take every day.  Both up and down.

There's the elevator, there's nothing wrong with it per se, apart from its pronounced state of ennui, the slowest and most depressed elevator I've encountered, and I've lived with a few.  But to go three floors in it is very poor show, faster and better to walk, even with groceries and a couple of trips.  (But glad we have it all the same.)

Air still bad but there is more light - as you can see from the stairwell.
