We didn't have the chance to meet Valentina, because she was travelling, but we met her father, Orfeo, who was very kind and lovely.
The apartment is very well situated, 15 minutes walking to Vatican City, and 2 minutes from the metro line A or regional busses.
The kitchen was well equipped, you have everything what you need there.
Valentina answered very fast your questions, so the communications went smooth. We would definitely recommend this apartment.
