I don't think I ever saw anyone in Italy with a fancy coffee machine. They all use moka pots at home, and go to the local cafe if they want an espresso made with a machine.
That was one of the best parts of traveling in Florence. You could pick a different café every morning and by the end of a week long trip you'd still haven't tried all the café's in a two block radius.
Yeah - it's legal to open one pretty much anywhere - compared to the US where they're illegal in most areas of most cities. It's nice to be able to walk to stuff!
