I am posting this as we had booked this hotel for a visit February 2013.
The day before flying out we were told there were "heating problems" and were advised to re-book another hotel.
We checked this hotel when we arrived in Florence and it seemed to be boarded up and "under renovation".
So you are advised to check the situation before deciding to book.
I think this was probably more the fault of the booking agent who maybe had not removed the hotel from their books.
