This was a wonderful apartment. The location is fantastic, but the apartment itself was very comfortable with all of the amenities, and was exactly as advertised. It is 4 flights of stairs up, so not for someone who has difficulty walking.
Any questions we had about anything were promptly and competently answered by Alessandra; she was very helpful, as was the guide/instructions inside the apartment.
My family and I (spouse plus 2 teenagers) really enjoyed this rental, and would absolutely use it again the next time we are in Rome.
