First, Maurizio's cummunication was excellent. He was always ready to reply and kept us up to date with all details.
Second, location is within minutes of the Colosseo, the Roman Forum, and the Papal Archbasilica of St. John Lateran.
The flat is perfectly described in Maurizio's ad, and all pictures are 100% accurate.
Maurizio was a great host who provided maps, instructions and even cookies during our stay.
