We have spend two wonderful weeks in this apartment. The flat is very well, the shower is amazing and the terrace is perfect to have breakfast with the sun of Rome.
We haven't met Tiziana but when we arrived everything was prepared with some food (fruits…) in the fridge and all the instructions for using the electronic material of the apartment.
You have trams and buses near the flat to reach easily the center of Rome (and soon the third subway line…). Pigneto is a place not so touristic and that's perfect to have a drink or eat something. If we have to come back to Rome, we will return in Tiziana's flat !!!
