The stairway is big.  Probably because originally it was not the entrance to a home, but to  upstairs businesses.  Many old buildings have steep narrow stairways, not true here.  This stairway is wide with deep treads, an open straight climb.   But if you fall down these steps you will probably roll right out onto the sidewalk.  It still has the original woodwork, as does the whole apartment.

In this view you can see doorways which originally would have been entrances to the different medical rooms.  For family living they were closed off halfway down the stair rail with various closets.  Entrance to the whole apartment was through the kitchen door.  Opening it all up and using the original hallway will create better flow, letting in light and visually increasing the small space.  The doorway in the background (right) in the middle of the wall will be closed off since bedroom entrance can now be gained via the hallway.  The two doors on the left are to the bedrooms, and there is also a doorway between those two rooms as well which will be taken out.  Above the doors are transom windows.  The two here have wood-grained contact paper over the glass.  When that comes off even more light will stream in.  The bare studs leading to the living room will come out and that room will be open all the way to the stair rail.

Here is the opposite view from the bedroom doors down the hallway that had been closed off.  The doorway above the stairway is to the bathroom, one to the left was the main apartment entrance to the kitchen when the hallway was closed and will be taken out, and the door on the right leads to the only skyway in town.
