Where are we?
Oh, it looks like we're in the teens somewhere.
Well, when we get to twenty, tell me. I'm gonna throw up.
At this point, most people are also probably aware that stairs in the Biltmore Hotel in Los Angeles were used for this scene. I'm not sure who in the GB fan community made this discovery, but I do want to express gratitude to any who have shared information about it before me. I wouldn't be able to do this article without all of that previous work. I know it was discussed on GBFans by Kingpin as far back as 2010, and Proton Charging has provided useful information about it in recent years as well. Additionally, Spook Central has provided some good information on the stairs, as well as probably the most comprehensive article about scenes shot at the Biltmore:
"Spook Central: Filming Locations: Sedgewick Hotel"

That being said, the filming location of this scene was most likely first mentioned way back in 1985, in Don Shay's Making Ghostbusters book. This comes from the notes on page 165:
To help illustrate how this was done, it helps to see the scene next to the matte painting that was used to both add height and width to the stairs:
Now, what I have yet to see online is a guide explicitly directing people to the correct stairway. The Biltmore actually has 4 stairwells with similar architectural features, numbered #1-4 in this map from the 4th floor of the Biltmore:
It's worth noting here that none of the colors match up anymore, as the walls, handrails, and balusters were all repainted at some point after the filming of the movie.
Now, it is easy to confirm that stairs #3 and #4 were not used in the movie, as the steps in those stairways ascend counterclockwise, whereas the steps in the film ascend clockwise. However, stairs #1 and #2 both ascend clockwise.
What I've found through a little bit of investigating is that stair #2 is clearly the stairway that was used for the film and I want to explain why as I've noticed a number of people assuming incorrectly either that it is stair #1 or that there's no way to determine which stair it is.
To prove that stair #2 is the stair that was used, we need to look for unique features. I've identified two of them: some kind of encased wire to the left of the guys and some molding on the wall behind them:
If you go to stair #1, you'll find neither of these identifying markers (nothing on the back wall and no wire):
Now, when you go to stair #2 on the other hand, you find the exact same identifying markers:
Note that the molding on the wall behind the guys is actually part of a large door panel on the wall. Also, I think it's important to observe that the stairwell is actually rectangular. So not only did the matte painting expand the stairwell upward, but it also widened it, making it more square in shape.
Now that we have the correct stairs, how do you get there and how was the above picture taken to mimic the film shot? This has all been explained elsewhere before by others, but I'll repeat it again here, including directions to stair #2.
To get to the stairs, you'll want to first take the hotel elevator. Getting off on the 3rd floor or higher (depending on how many steps you want to walk down), follow the map to stair #2 (you can partially see it from the elevator hall, but basically, it's a quick left and quick right and you're there). Next, you'll essentially just descend stair #2 almost all the way to the bottom (which is the 2nd floor, used primarily by hotel staff).
The final photo I took was from the 4th and 5th step up from the bottom of the stairs (i.e. the 2nd floor). It's not perfectly aligned, but it's pretty close to where the camera would have been positioned for the film.
