Even though Partizia was an "unexperienced" Airbnb host, everything went very smoothly. Communication with Patrizia was always quick and she provided all information needed.
Arriving at her place we were welcomed and shown around.
The apartment itself looks just like the pictures and is very nice, clean and bright. We were two adults and two children and had enough space. There is a comfortable bedroom and a bed couch in the living room. The kitchen is very well equipped and Patrizia had bought us some food (biscuits, butter, milk etc.) to start with.
The flat is located just across the river from Testaccio (great area for bars and delicious restaurants) and very close to the Trastevere train station. You can walk in 25 minutes or so to the Colosseum or take a bus that leaves almost in front of the flat. We stayed for four days and did everything on foot.
Summarized: great apartment, location, and value!
