There is very little to do at Milan besides eating. There are just a few touristic attractions, such as the duomo, and as so they are usually over crowded in a way that's not pleasant. The metro system and buses are confusing and it's hard to get information. Streets are not clean at all and all the time I felt like I was walking in a bad neighbourhood, despite staying in the city center. Markets and stores also operate on weird hours - couldn't find places open neither at 11 AM nor at 5 PM.
