I loved staying in the Piazza della Passera its a very special part of Florence.
Giuditta's apartment is in a perfect location overlooking the piazza like a movie set.
It can get a little noisy in the evenings but I was prepared for that and Guiditta informed me of potential noise in advance as well.
I would only point out that the apartment was very spare especially the kitchen, and offered no real cleaning amenities. It would be difficult for longterm stays or really anyone wishing to stay longer than a few days. However, it is a very simple and clean apartment, minimal and basic, and you'll find everything you need just fine for a short term stay.
