I made this reservation for my parents, and I was in contact with Maria Cristina, as my parents do not speak English or Italian.
My first opinion about Maria Cristina was really good. The second, even much better.
She is really easy going, giving a lot of information, and allowing my parents doing early check in and late check out. My parents are not surprised easily, but with her, they were.
About the appartment, and always about my parents words, was really good located, with metro, bus or even walking to the city center, and is a really beautiful place to stay, inside a traditional Italian quarter. This place deserves each cent that we have paid for it.
I am just waiting to my next trip to Rome to live this experience by myself.
Thanks so much, Maria Cristina.
