Maria Cristina was wonderful to us. After an overnight flight from Ethiopia, she arranged for our transportation from the airport to the apartment and then met us at the apartment in the early morning hour (6 a.m. or so). Maria Cristina gifted us a bottle of wine which we enjoyed later in the day.
The apartment is beautifully furnished and situated so that you can catch morning and afternoon breezes. There are two grocery stores nearby and very close to the Vatican.
I highly recommend this apartment for your Rome stay.
