A very cosy and quiet place near the EUI (particularly Villa Salviati). It was the perfect retreat spot for me to stay for a while and complete some thesis-related work. Very appreciative of Sara and her family's kindness. Other than the occasional bird chirping, rooster in the distance, or siren far away, it was quite quiet and tranquil. That's not always the case in Florence.
I noticed a few other reviews that mention the traffic on the main road. While it can be a little bit of a tight squeeze for pedestrians and cars, I think I would just say that this is the case for much of the outskirts of Florence - nothing unique to this road in particular.
Overall, I would say that if your plans include spending a lot of time in the city centre, to consider having some form of transport to get to and from. I took the journey on foot, and I enjoyed that, but it is a decent walk that can get tedious. If renting a car is not in the cards for you, there are rental bicycles freely available throughout Florence that would substantially reduce the commute time between Sara's place and the city centre.
