Floria's place is ideally located right next to the Duomo. It can be noisy at night (on Saturdays especially) as it is in the middle of the old town. I would recommend it for 2 people but not more. Floria was a very welcoming host, she let us check in early which was very convenient and was always very quick to answer emails. The flat was very clean, decorated with simple and elegant taste and also very convenient!
