I highly recommend this accommodation as I had the pleasure of staying in Claudio's travel room for 7 nights.
The apartment is located in front of a tram stop that will transport you directly to the central station in Rome, and has eateries and grocery stores nearby. It was a very clean, nicely decorated and spacious room.
As for Claudio himself, he was extremely helpful, polite and able to answer all of my queries regarding Romes' attractions and transportation. He also gave me some lesser known recommendations that live up to the more mainstream destinations. He was even polite enough to escort me to the bus stop to make sure I went to the airport on time.
Thank you once again, Claudio!
