I had a great experience staying at Roberto's apartment. The location is fantastic -- a 10-minute walk to the Vatican and 1 block from the Metro station. I was traveling alone and felt VERY safe in the neighborhood and on the Metro (which always had lots of people on it). I didn't arrive in Rome until later in the evening, and Roberto had no problem meeting me late (we arranged prior to my booking). He contacted me once during my stay to make certain everything was going well and arranged a cab to the airport for me. A great experience. I would definitely stay there again. For light sleepers (like me), bring earplugs or have a white noise app on your phone. I slept with my white noise app and had no issues.
