My friend and I stayed in house of Vanessa and Stefano for about 6 days. Stefano was very friendly, positive and hospitable man, also he prepared for his guests breakfast and always helped them with different problems.
The flat is situated near Cipro metro station and Valle Aurelia station, bus station and near Vatican. It will take you for about 15 minutes to reach the center or you can go by foot and it'll take you 40 minutes, but I don't think that it's too far.
Stefano, grazie mille)
