Milan is quiet and a bit industrial; it's certainly not as bustling and vibrant as Rome or as culturally relevant as Florence. But, it is a lovely two-day respite on a Euro-adventure.
In discussing favorite cities, friends and I always give points to those that have a distinct aesthetic. Could you be dropped in the place blindly and instantaneously be able to tell where you are? Both New York City and Paris fit this description, as does Berlin, in large part due to its unique street art culture.
