Very nice airbnb in an excellent part of Roma, just one minute to cross the river and head to the centre, all walking distance to main touristy spots. If not, I suggest the bus, just round the corner , they ran frequently and more than one will take you near the tourists attractions. Make sure to buy the tickets beforehand and validate them as you hop on the bus. Also i used the app InTaxi, and you can “call” a taxi ( really you dont call but just put your location and the app search the nearest taxi, very much like Uber but you pay the taxi driver directly.) We took the bus to Trastevere a couple of nights as it is a good 30mns walk.
The air conditioning was a real plus as it was extremely hot when we were there, also excellent mattresses and the no noise at night. A bunch of great restaurants right next door so if too lazy to walk back in the centre, you have some all around the airbnb.
Chiara is a great host as is Lorenzo who let us in when we arrive. Communication was good and Chiara was very helpful to organise a taxi transfer from the airport and back. All in all i would greatly recommend the airbnb
