Roberta is the friendliest Airbnb host I've ever had the pleasure of meeting. She was very responsive to any questions I had via Whatsapp (responded within 5 minutes to my numerous questions). She also went above and beyond to gift us with a chocolate Christmas gift, allowed us to check in early, arranged for a Mini-van taxi from/to the airport to her airbnb, made reservations for us at her some of her recommended restaurants (that were amazing) since they only spoke Italian. Her place was also very well situated being a 10 minutes stroll to St. Peter's Square, 10 minutes to Trastevere, 30 minutes to Spanish steps/Trevi Fountain/Colosseum - this allowed my 81 year old grandmother and my family to easily walk and enjoy all the site in Rome.
It was also very safe, with a door that had 4 locks and automated metal gates for the windows - and the fact it was across the street from the Police Headquarters of Rome.
