A good way from a German city! (4)
I believe the answer is:
bonn
'a german city' is the definition.
(city in Germany)
'a good way' is the wordplay.
'a good' becomes 'bon' (I can't justify this - if you can you should give a lot more credence to this answer).
'way' becomes 'n' (Compass direction - North).
'bon'+'n'='BONN'
'from' is the link.
Can you help me to learn more?
(Other definitions for bonn that I've seen before include "Capital of the former West Germany" , "Beethoven's birthplace, old capital" , "Capital of West Germany, 1949-1990" , "old European capital" , "W German capital 1949-90" .)
