his address includes the following letters :
b,d,e,f,i,l,n,o,r,s,t,u and y
so there's no a,c,g,h,j,k,m,p,q,v or z
unsurprisingly one of the words in the address is street.
I think the u and the y might help - dont think they would be common in street names..
(p.s. there may be more than one of each of the letters)
