for the tourists:
when you need a tourist guide in Milan, just ask me, Marco Guido. I was born in Milan historic centre, I always lived in Milan historic centre (for decades), and I always will be in Milan historic centre. So you can hardly find someone who knows better the city. I've also studied in a history&culture path at a Milan university.
You know, nowadays many people go to live away or abroad, not only in Italy, and the natives living in their city are diminishing.
I've got experiences, I've always been around the city with tourists, people coming to visit me from abroad.
Milan tour includes visiting Duomo cathedral, museums, etc., your choices, anything you're interested in (of course it also depends on which period you're coming, so there would be different things to visit and events to attend)
