Surveyed the courtyard. There's no name signs whatsoever. One door has a hostelword sticker and a sign that says "If you want to get in, call this number". Old pictures on the internet confirm that it is the same entrance - https://www.eurocheapo.com/riga/hotel/riga-student-hostel.html .
I've updated the location to better match the entrance, likely nothing more to be done here.
Closing.
