The reason why I love Bologna apart from the fact that they have H&M (they have the new Madonna line, yes I am shallow), is that it is such a nice cross between Florence and Siena. In terms of size, style, level of 'touristiness' etc.
Florence is beautiful, but too touristy at times. Siena is a great place to live in but too small. So Bologna is a nice hybrid of the two. Tons of brick-walled buildings and churches. Plenty of cute shops. May not be the top choice for many people when they head to Italy for a vacation, but still worth a visit! Recommended! I Approve!
