it says this:
"If you do not stay in a tourist accommodation, even though you are staying for a period less than 3 months, you are required to report your presence to the Questura. "
I never knew this and have never done this. I stay in my apartment 7-14 days at a time and have never registered. Does anyone have any experience doing this? I'm afraid if I start registering now, they may figure out that I"ve been doing it for awhile, since the apartment has been in my name for 1.5 years. I am not a citizen of any Schengen country.
