So far, Rome is certainly my favourite city in Europe. I intended to spend 4 days there, but ended up spending 12.... and I am still not done. I would love to go back as soon as I can and redo everything I did and do everything I missed.
Insider Tip:Check out the world's smallest movie theater, Cinema dei Piccoli, in Villa Borghese. If you are a film buff, catch an old movie at Casa Della Cinema at the hall right next to it. Try the Tramitzini.
