Giuliana was a perfect host, answering my questions quickly and informatively. She even had a back up just in case she was unreachable, but that wasn't necessary for me.
She even went out of her way to book four restaurant reservations for me, two of which were last minute, but she made it happen.
About a few minutes walk from Cavour station, there are two of them going in different directions, so first-time metro users be careful which one you get on! As a New Yorker, I could figure it out relatively quickly. Giuliana would be able to explain very easily.
