We needed a place close to the train station so we could get to the airport for an 8am flight without an expensive taxi ride, and this was it! Nice 5-6 minute walk to Termini, but also lots of great restaurant options and the Colosseum was only about a 10 minute walk. The street is very quiet but close to a main street for ease of access.
It would be a little hard to find on your own, but Marco was waiting outside for us to let us into the building and showed us the tricks for unlocking the doors. He was not onsite the whole time, but he was very helpful and responded quickly to airbnb messages.
