We stayed at Augusto's place for four nights as we explored Rome. It is a 15-20 min walk from the heart of Trastevere, which was slightly longer than we expected but it was okay. Right around the corner though is the metro line and plenty of buses. Once we figured it out it only took us ~20 mins to get from Augusto's place to the historic district of Rome and it was incredibly easy to navigate from there. We loved our time at Augusto's place and it is exactly as he had described. The place is beautiful, surprisingly large for typical 1 bedroom apartments in Italy and very clean. I would caution people looking for a place within walking distance of all the major sites as it's not really, otherwise if you're okay riding public transit (as we were) I would definitely recommend!
