We stayed at Andrea's place for 4 nights. The location really is only a couple minutes walk to the Colosseum. It was really convenient for touring ancient Rome and an awesome view to see when we left the apartment every morning. It's also right by a metro stop so when we needed to get to the train station it was very easy. If you plan to spend majority of your time in areas near the Pantheon or in the trastevere neighborhood keep in mind it is a bit of a walk to get to those areas (a mile or more). The apartment was quiet most every night except we did hear quite a bit of street noise late on a Friday night. Andrea was friendly and very quick to respond to any messages I sent him.
