I was contacted by the lobby butler, Ombretta, few days prior my arrival and I send to her some requests for my arrival. My arrival was on February 6th, 2012.
When I checked in, she was there and when I saw her I called by her name, she automatically answered me by mine. After meet her and Receiving all the attentions, more than I expected, see how professional and efficient she is, I can say she is the finest in the industry. Thanks Ombretta!
The location is premium, No more than ten  minutes walk for all the main points of interest. Sitting at the Arno river the views are awesome. The hotel was reopened in full on september after an extensive renovation. It is the best, no other place to stay in Florence. The rooms are huge, they have Medici style. Florentine style and suites. I had a Medici river view: Very cozy and comfortable. The bed did not invite you to wake up and the bathroom Was not so big but perfect, more than I expected.
The linens are great, very high quality. It has a walk in closet too. Everything was immaculate cleaned and working. 
The staff of the hotel: the best. Everyone knows you by your name and there are very helpful. The concierges are also the finest in the industry. The front desk staff: wow!
I only had breakfast at the hotel and I was lucky that Daniela took Care of Me everyday. The amazing thing:  one morning I cross the "piazza" to have breakfast at the Westin (sometimes guests from
One hotel can eat at the other) And... She was there giving a hand to them Too! 
I am very sorry Florence but you will be the second reason to come back. The first is the St Regis Florence.
