We walked from the train station (~15mins) to Francesca's apartment, where she was waiting outside, she took us through the apartment and explained the checking out procedure (very convenient to have a luggage store!) The apartment is in a nice area of the city , with great restaurants and bars less than 2 mins walk away. The Pitti Palace is about 5 mins walk, the Ponte Vecchio is about a 5-10min walk and Uffuzi is only 10-15 minutes walk...no need to take a taxi anywhere :)
