We recently stayed at Firenze Number Nine and were looked after brilliantly from start to finish. We stayed in room 107 which has one of the amazing ceiling frescos, huge TV, and a beautiful bathroom. This is definitely the right hotel and the right room if you're looking to impress / spoil someone. The staff could not have been more helpful, in particular Yanni - I proposed to my girlfriend in Florence and he made all the secretive arrangements for me, including roses and champagne in the room and tickets for the Uffuzi and Accademie. Awesome breakfast, wonderful spa next door that's free to use for guests, and all this a minutes walk from the Duomo, and 5 mins walk from the train station. I can't recommend this hotel highly enough.
