Great listing which is close to transportation (no more than a 3 minute walk). You could walk to the touristy parts of Rome (30+ minutes depending on where you are going) but transport is so close and convenient. The apartment itself is on the ground floor and has a kitchen and bath. All was VERY clean and the bed was comfortable. It was also clear that the hosts thought of their guests as there were some extras that most Airbnbs don't have, like an extra duvet, hangers, washing machine, etc.
We did not get to meet the host but he was very responsive on the phone.
One thing to keep in mind, there is a city tax that must be paid in cash in full for the stay during check-in, but that's the case with all Airbnbs in Rome from what I gather.
Overall, would recommend this place in a heartbeat. :)
