Claudia is a great host, many books on Rome to help you settle in. We walked back in forth from the apartment to Rome and Trastevere.
There was an outdoor evening festival along the Tiber that starts at the ponte sublico edge of testaccio. The best pizza in Rome as told by locals is in testaccio don’t need to go far. If you walk out of the apt and head toward marmorata away from the Tiber deeper into tesstacio and make a square around the apt you will find plenty of little markets and places to eat. We learned that a bit late and went into trastevere too many times.
Enjoy
