We just returned from our trip and had a wonderful stay at Costanza's place. My family of 4 had plenty of space. It was nice having 2 bathrooms. Constanza's daughter Francesca was there to greet us and orient us in the flat. We were given a welcome bottle of wine, some food in the fridge, milk, bottled waters, snacks, coffee and tea! All this exceeded our expectations. Francesca assisted me in securing a taxi on our departure day, and verified our train to Venice was guaranteed since there was a bus/train strike on our departure day. Her help was greatly appreciated. The walk to the Duomo and other city sites was about 15-20 min. We really enjoyed strolling around Florence. I would not hesitate to stay here again.
