Lavinia is a great host. Soon after making the reservation, she immediately sent us detailed instructions on how to get to her place. She was very responsive to all our questions prior to our arrival. She helped us beyond what an Airbnb host is responsible for.
About the apartment. It’s very cozy and clean with fast WiFi. The location is safe and close to the Vatican (maybe 10 mins walk). All the other tourist sites are within walking distance as well. Plenty of restaurants nearby. My only complaint is the extremely low water pressure in the shower.
