Full of Hidden Treasures
I have traveled to 14 Capital City's this year, and Rome was on of my favorites. Honestly, I was initially put off due to travelling around the city center being difficult (only 2 metro lines around the outside), but this was turned upside down and I was glad to have walked places. It forces you to explore the city more. To get lost. After this I'd be tempted to walk places instead of relying on buses, trams or trains. It is full of history, as beautiful as it is in pictures.
Insider Tip:When you go out in the evening to eat, don't settle for places just because they're nearer the metro stops. Walk further into the center and experience authentic 10/10 food for much cheaper.
