When routing through stairs, instead of the following.
- Turn left onto unnamed road
- Slight right onto unnamed road
Indicate the following.
- Turn left onto unnamed road
- Go down the stairs
- Slight right onto unnamed road

Possibly even mention the level:ref or level (with regional ground floor number correction)
I feel that this helps keep on track when reading the text instructions. The level would help a lot indoors too.
Edit: Escalators too
I just now noticed that Valhalla supports indoor routing better as said here. It says "Take the escalator" and "Take the elevator to Level 3" and uses "walkway" instead of "unnamed road"
