first 11 results seemed all perfectly ok to get there :)

this is a "housenumber" (it:numero civico), but then people have addresses
(it:indirizzo). So somehow the people (businesses, entities, etc.) are
linked to their housenumber, and as it seemed overkill to have relations
for this linkage we usually put address tags on the features as well.
(There's some evasion attempt by adding feature data to the entrances and
gates, but it has topology issues and combines different "things" in one
object, or by keeping the feature address unknown).
