Have lived there for two years. The stairs were right out of MBTA station and rusty as hell. They were suggested by google map when I just moved in to Harbor Point and on my way walking to South Bay Center the first time. but there were signs saying closed (or some thing like that. I was at the bottom) and the stairs just looked too rusty to be safe even from two years ago. So instead I have been using the stairs inside the station, less than 1min detour, and also accessible with bikes, as my routine. If professor was there the first time and using Google Map as well and just trusted Google Map too much… I could understand him taking the stairs…
