Which five-star hotel in Florence, Italy is better?

My first impression is Firenze Portrait Hotel, which is owned by the hotel management group Lungarno Collection run by Salvatore Ferragamo family, and is close to the most attractive boutique of Via Tornabuoni in Ponte Vecchio and Vizioz. Hotel guests can visit Le Ferragamo Museum in Salvato for free, and even get a discount in the boutique. In addition, Grand Hotel Villa Medici, Helvetia and Hotel Bristol are all good choices, and the environmental service is also good.
