This place was a little treasure. It's on a safe street that is near some in-building hotels as well and we were able to walk to the underground metro in a few minutes or take the bus. Almost every night we went to eat at local places and explore the town. Sometimes we were out walking as late as midnight and felt pretty safe.
The spiral stairs leading to the bedroom loft is small and so is the shower if you are of larger stature, so keep that in mind. (I'm 4'10, so that wasn't a problem, but you probably might knock your elbows if your luggage is gigantic up the stairs or in the shower.)
The host was amazing and met us to show us how to get in and use the place. She even had disposable maps and circled places that were popular and gave us a reference for a local Italian place nearby. If you are staying for longer than a 4-5 days, I recommend getting a week pass for the train and buses. Using them 16 times gets you your money's worth.
The host also offered to arrange a professional driver, nicer than an Uber, to go to the airport for about 55 euro. That was worth it for us for convenience as well, because dragging our luggage on cobblestone to Roma Termini was a pain in the butt. It would have cost us 15 euro a person (we had 3) to go from Termini to the airport anyways.
I HIGHLY RECOMMEND THIS.
