Great location for all the sites: 3 minute walk from the Vatican 2 mins from the metro! There is no free parking on the street where the flat is found but there is free parking just 800 metres away. Pointing towards the Vatican turn left left immediately taking via Pompeo Magno continue for 600 metres straight on at the large roundabout and on the LEFT adjacent to a church with railings park there for free amongst the trees, the right hand side of the roads is 4 euros for 8 hours which is not bad ! Left car on left for 3 days with no problems !
