We had a wonderful stay in Rome at Alessandro's Airbnb during our 4 night stay. The location was perfect for our group of 7 with easy access to the buses and easy walking to all the major sites and resturants. You can literally catch a bus in any direction just a few steps from the apartment. We were orginailly going to purchase 3 day bus passes for everyone, but we found it cheaper to just purchase one-way bus tickets at 1.50 Euro instead. Since everything is so close, we only used the buses 6 times.
