Don't hesitate to book this Airbnb, it was great! Good location, about 10 minutes walking distance from the Colosseum, about a 10 minute direct bus ride from Termini train station (bus #714). The host met us around the time we arrived from the train station, explained how to get in/out of the place. She was very nice and welcoming. The place itself is carefully laid out, bathroom is big enough to use comfortably and had all the amenities we needed. I highly recommend.
