What do I need to know before moving to Milan?

"Milan is Italy's second-most populous city and is known for its stylish architecture, fashion, cuisine and historic sites. The city centre is home to stylish shops, upscale restaurants and some of the country's top universities. Milan is an ethnically diverse city, with a large foreign population due to its position as the country's financial and business hub. Public transportation is excellent, with metros, buses and trams. The cost of living in Milan is higher than other Italian cities, so it is important to get to know the city before deciding on a place to live. As Milan is mainly a Catholic city, it is important to recognise and respect the major religious holidays and cultural customs that the city has. Weather in Milan is variable - summers are generally hot and humid, with occasional storms, and winters are typically cold and damp, with some snowfall," said another expat in Milan, Italy.
