We stayed 5 nights with my family at this airbnb and I really recommend you this place.
The location is really good and calm you can find groceries stores, restaurants, shops, it's not located in the center but bus station is at 2 min walk and the metro stop (Cornelia) is at 8/10 min walk so don't worry about joining the city center.
For the check-in we arrived really early but the host was nice and arrived a few minutes later to open the door (thanks Stefano!)
We really enjoyed our vacation in Roma thanks to Simone&Francesca!
