Francesco has all the required information well written in English on the page that appears after booking. He was very welcoming, I got a few hours late but he was kind enough to stay for me.
He did answer all my questions about Rome and checked for the ones that he wasn't sure about.
He hosts professionally and I loved the fact that he gave me the keys to the house and I was totally free to roam on my own schedule. He also let me use his washing machine for all my laundry multiple times.
His place is near metro station and I didn't have any trouble getting to the city center.
Highly recommended!
