My wife and I are going to be in Rome early October for 4 days. She has been researching like crazy and advised me yesterday that she envisions us using public transportation there quite a bit, more so than Florence or Venice. Just curious if anyone has had any experiences in using public transport in Rome, or Florence or Venice for that matter. I’m not adverse to the notion per se, went all over Paris and London using public transport with no issues, just curious if anyone has any experiences they can share. Any other thoughts, recommendations happily received. Ciao.
