A top city to visit in Germany
The Cathedral itself is enough reason to make a stop in the city. I walked around and looked at the other stuff and it was alright. As a traveler nothing is outstandingly spectacular, but if you don't get to travel then the sites should all be pretty cool. Have a few glasses of the local Kolsch bier. If you are a traveler this city looks like it has a pretty good nightlife, I didn't get to go out in it, but I'm positive it does. There's a lot of diversity and it's pretty busy. 2 days is fine.
