We had a nice stay at Fiorella's place. It was very clean and enough space for our needs. We really appreciated the little details and toiletries she provided. The only issue we had was that it was farther away from the city center than we expected (about 15 minutes to Termini and 40 to the Vatican) but it is really well connected to public transport even throughout the night.
Fiorella was a very hospitable host. The check-in was no problem at all even though we arrived later than expected and she even waited for us at the tram station. She was always quick to answer any question and even asked us a few times if we needed anything.
