Well, I don't think I've been to enough cities to name a least favourite (seems a bit mean to say 'such -and-such is the WORST city!' when I've been to maybe 15 cities for enough time to judge how nice they are and have no idea about any others), but my favourite city would be Paris. It is just so beautiful and clean and magical. I love Rome because of the history and it is also very beautiful, but Paris is just so special. Plus the metro is totally cool
