I had a wonderful stay at Aldo's! The room was spacious and comfortable, the building was lovely (with an elevator!) and the location was incredibly convenient (so close to the metro, busses, AND the Vatican). I felt safe walking home late at night when I missed the last bus*, and when I was leaving for the airport early in the morning. As a host, Aldo was gracious and communicated very quickly. U can't say enough good about this place!
(*most busses start their last run at midnight, FYI, and seem to make that last route faster than scheduled)
