Ilaria was very helpful and a gracious host. She met us at the apartment and explained to us everything in detail that we needed to know. The apartment is spacious and well appointed. If you are visiting Tuscany with a family or a group of people this is an ideal set up. Car parking in the historic city centre is difficult and few parking garages that are there are expensive.
Italian ZTL (restricted traffic zone) laws restricts vehicular traffic in the centre of town to residents, taxis and buses. Even if you enter the ZTL by accident and leave right after you will be fined. This is very well monitored.
Ilaria and Stefano's apartment comes with secure and free parking behind the house. This was ideal for us as we had a car for the 7 days we were in Tuscany. We stayed in Firenze but drove to Pisa, Chianti Wine Region, Siena and several other day trips.

There is a supermarket around the corner from their place which is very convenient. Several buses from outside the apartment took 10 minutes to reach the Stazione Santa Maria Novella (Firenze Central Station) in the town centre from where everything is within walking distance. As advertised the WiFi in the apartment is proper high speed. Both Ilaria and Stefano were helpful with answering our questions and offering suggestions.
