I had a nice visit in Rome hosted at Leonrado's place, clean and nicely furnished, on the 5th floor of a building located in a quiet area, even though nearby a rather busy street. It is 1.5 km north from the Piazza del Popolo, marking the entrance into the city center, and you can either walk or take the tram 2.
Leonrado was very friendly and helpful, thanks for this enjoyable stay !
