Niederdorf or the old city is probably the best part of Zurich..
When you visit Zurich do notspend much time at bahnhof street, just pass to the niederdorf street and oberdorf..
Niederdorf is a narrow street which is open for pedestrians, surrounded with old, nice Zurich houses, Many Cafes, Restaurants and shops..
Niederdorf is paralel to Limnat quai, Which is the waterfront of limnat river.. Niederdorf starts from the "Central" square.. Which is just in front to the train station..and ends at Gross muunster, the biggest church of Zurich.. And from there oberdorf street starts..
I have enjoyed a lot walking and touring a long the Niederdorf.. Going deep in to narrow roads.. Drinking in the cafes and window shopping.. And I pitty the time, that I have loosed on bahnhof street..
The heart of Zurich betas at Niederdorf.. So take your time there..
