On #11728064512 I've tagged the address node, it's a plaque visible from the street. Again, also on that one the streetname is written on it, but I couldn't read it since I was in a car.
Also: #11728064512 I'm sure is referred to Via Palmiro Togliatti. But it looks strange to me that the numbers I've tagged on the cemetery are all sequential and non-alternated (as if it was a square). That's one other thing that made me decide to not add the addr:street tag.

I know how to do this. I do what I can and what I know for sure. I do what I can, at my best. If there's something missing I will fix it when I can, or if someone else is faster than me it's ok. Do you want to help or to complain?
