My experience at Roberto's flat was absolutely wonderful. He was very kind and gave me some excellent advice about the area, particularly about food and things to see. I highly recommend that you listen to his advice. The flat is not far from the metro station, perhaps a 7-10 minute walk depending on how fast you walk. From there, you can easily go anywhere in Rome. The flat is spacious, clean and very modern. It was a very comfortable stay and I had everything that I needed. I felt very safe and secure as well. Roberto was available to answer any questions. He has my highest recommendation :)
