Arianna and her husband were very welcoming and accomodating. The room was clean and cozy. The location wasn't exactly where we were expecting, but it was conveniently within walking distance of Ostiense station (2 stops away from Roma Termini, and one stop away from Trastevere) and Eatily. If you're comfortable navigating public transit, that's probably the best mode of transportation, but we ended up using taxis to simplify things. This was more expensive, and the drivers usually weren't aware of the address, but we could just tell them to take us to Eatily, and then we had about a 2 minute walk from there.
