We would highly recommend staying in Claudia’s place. It was just perfect. Claudia’s daughter provided us with all the points of interest, great restaurants, how to get around with transportation. By the way you can take the local train down to Roma Termini for 1 euro. And of course from the Termini to Gregorio VII stop and it’s an easy walk to the apartment. Be aware not to take a cab if they don’t have a meter or if they don’t take a credit card. The cab drivers will take advantage if you just show them an address and ask them how much. It will be €35 when it should be €10. Be aware!!
