Yes a bit lucky but just draw the 9xxx km circle around the MY BK and then I saw the circle go straight through Florence (also Bologna was a likely candidate). Then find a BK within 2.6 km with a fairly long street name and draw a circle, it intersects with the other circle in two places. The obvious one was the parking near Piazzale M.

I can also get the GPS coordinates at all times from your phone so it was easy to verify I was right.
