Three night stay. Never got email re access pin to check in, but easily done (in the rain) outside the door. There is no front desk or staff.
15 minute walk from train station.
Got the large room with corner windows, nice view, beautifully furnished room, with fridge, teas, coffee. And a Mozart bust!
Good location - 2 blocks from Linzergasse, a main walking street down to the river. Restaurants, shops, pharmacy, groceries all nearby. Quiet at night. Only caveat is no info on emergency services if needed - communication via chatbot or what’s app. Felt isolated that way.
Otherwise a great place to stay while enjoying Salzburg!
