Lately, lots of these little bugs have been lurking in my house in Italy. Should I worry? I'm curious to know what they are. For reference, the 2 cent Euro is 18.75 mm in diameter.

It looks like a carpet beetle larvae(Anthrenus verbasci) to me. This seems to fit considering you found it in your house, which is one place they are fairly common. I would not be able to tell you if you should be worried, I am not a biologist.
