When my wife and I got there, Mr Valter was so nice since the beginning. Met him last day, even though helped us by text messages. Mr. Valter's daughter, Chiara, received us and explained us about the place and gave us recommendations where to go and visit, and she did it in a SO KIND AND NICE WAY!! She was addorable, since the beginning she was amazing. The place is really close from vatican (1 street) and really easy to get to.
When we go back, we will be there with Valter and Chiara again.
