Federico's place is right in the heart of Florence, within easy walking distance of all of the city's main attractions, and just a few steps away from the entrance to the Uffizi Galleria. It was also close enough to the train station that we were able to walk there with our wheeled luggage.
His apartment was beautifully furnished, and he was friendly and helpful in suggesting to us his favorite places to eat around town. We had an evening train on the day of our departure, and because Federico didn't have another guest checking in that day he was able to be flexible with us on a later check-out which was extremely helpful for our plans.
Thanks!
