Death registration in 1916 Warsaw. Where would I locate a "street map" to locate the addresses? #warsaw

Our Jewish Family History Research

Hi all:
I am posting information from a translated Warsaw death registration. I am hoping that one of our fellow members would kindly share where I may locate those 
addresses. In particular, House #670  is most important for my research. No street name?

Here it is:
Death registration took place in Warsaw in the 
Powązki, fifth precinct, on March 11, 1916
-Date of death:  March 10, 1916
-Place of death: House # 670

-Gersh Zilberstein, a tradesman, an adult living at 1 Bayun Street in Warsaw,
appeared in the presence of an adult witness -Nuson Moore, a house manager living in house number 8 in Warsaw.

Many thanks in advance.
