If you need a place to stay that’s central and good value (as well as stunning), stay in one of the Suite Apartments of the Johanna & Johlea. While I missed the night staying at Casa Tornabuoni, my father and sister loved it. For 210 euros a night, you get a two bedroom apartment minutes walk from the Duomo and the River Arno. If there are just two of you, then stay in one of the homily Bed & Breakfasts that Johanna & Johlea offer. Very Italian and very good prices, all with excellent locations in Florence.
