Altstadt
first visits, museums, the Frauenkirche, Semperoper and booked cultural days
Choose Altstadt when timed culture and a first encounter with the historic skyline are worth more than a neighbourhood-bar atmosphere.
Mostly calm later, but squares, tram corridors and event exits can remain active.
Do not assume every Neumarkt or Theaterplatz-adjacent room is calm; check street-facing exposure and performance-night access.
