We've spent 3 night at Susy's appartment and we really enjoyed the stay. From the airport it is very easy to reach the flat and Susy is a great host.
As soon as we arrived we felt comfortable, she explained us everything we needed to know and give us some info about good restaurants in the neighborhood. She speaks perfect french so it was a pleasure talking to her.
The appartment is nice and the room with private bathroom are clean. You can easily walk to any place in Rome, no need to take a taxi or a bus. Moreover the neighborhood is rather quiet (for Rome) even if we would have enjoyed a double-glazed window. Also there are some very good restaurant around her flat (we recommend E Cucina).
Overall this was a great experience and next time we come back to Rome it will surely be at Susy's!
