Nicoletta's place was perfect. I arrived late in the evening at Roma Termini before an early morning flight from Fiumicino. The walk between the train station and the airbnb was a brisk 5 minutes along a well-lit (for Rome) street. Check-in was a breeze. The room was comfy and the shared kitchen was full of amenities including coffee, tea and cooking implements. I left early in the morning, and again, getting to Roma Termini was no problem.
I travel a lot and live in near a train station in Italy myself and I found the atmosphere around the station to be normal. There are many shops and cafes nearby and many people around, which means people are likely to help if anything goes awry. I highly recommend this airbnb for its cute and clean interior, its price point, and its proximity to Roma Termini. Nicoletta was a perfect hostess.
