Tiziana is a very thoughtful and expressive host. During my short stay, I think I learnt more about Rome and Italy from her than from all the tourist spots I visited. It was a wonderful experience to chat with Tiziana over morning coffee, listening to the birds on her sunny terrace.
The apartment itself is located close to the Basilico S. Paolo station on Metro B line. Roma Termini can be reached in 15-20 minutes, and there are several buses running as well. Basilico S. Paolo which is very close to the metro station is also definitely worth visiting. Oh, and you get a wonderful view from the terrace of Tiziana's apartment.
Grazie, Tiziana! :)
