The apartment is beautifully designed and very cozy. Appliances and interior are brand new.
We visited in the winter and had no issues with temperature or hot water. There are three ACs to keep the apartment warm, the hot water boiler is sufficient.
The apartment is not directly in the center of Florence, but it's a small city and you can walk everywhere in 10-15 minutes. The area is nice with several great restaurants and a food market nearby.
