Location, location, location... And an awesome host as well! I stayed at Alberto's B&B for two nights -- the room has everything you need, a fabulous bathroom/shower (and more!) Plus, in the morning you receive a beautifully presented breakfast of fruit, pastries, cheese/meat. It's fabulously situated near the train station with easy (super easy) walking distance to Ponte Vecchio, Uffizi, and the Duomo; it's also next to a laundromat in case you need some fresh clothes for traveling. Note that the unit is up a few flights of stairs like most places in the city and there is some noise from street/bar but that dies down in time for bed. Oh-- and take Alberto's restaurant recommendations -- they were all fabulous! I can't wait to return to Florence and stay here again.
