We stayed here for a week for our 30th wedding anniversary. It was very clean, great location, and under 550E for a week. It was a short walk to many areas: The Vatican and of course St. Peter's, the Spanish Steps, a short walk from Piazza Navona and Campo de’ Fiori. Close to a bus stop too. We even ran into the Patheon on our way walking back from another site. Felt like a safe area to us. Initially, it was hard to find on our own, but we took a taxi from the train station for under 10 Euros and the driver knew right where it was. There is also a small grocery close by. Would greatly recommend this apartment.

Noticed my link didn't take: This is where we stayed:San Trifone Apartment 1-PIAZZA NAVONA

We traveled to Rome in 2010 and stayed in an apt in the Piazza Navona area. It was through Sleep in Italy and it was wonderful!! We had no problems whatsoever and I highly recommend them.

Have a wonderful time!
