My question is, I'd like to meet someone at a cafe who's address is an Ufer, for example Bismarkufer. Is it incorrect to say:
Lass uns in Bismarkufer 66 treffen.
Would a different preposition be used if you wanted to meet generally on the Ufer?
Lass uns auf dem Bismarkufer treffen.
It's hard to know what prepositions to use when!
