Stefano is a great host. He answers your messages fast and he is very informative. His apartment is as it is shown in the pictures and it had enough space for the 5 of us. It is near public transportation although the metro station near it was closed for renovations. Bus 185 goes in that area. It is near the colloseum. About 13 euros for taxi to the Vatican. Same amount for piazza navona. Good bakery for breakfast nearby. All in all - good stay!
