The apartment was ideal for our 5 night stay in Florence - the Duomo and other popular tourist sights are about a 10 minute walk away, with some great bakeries, a small supermarket and an amazing gelato shop just around the corner. I would recommend the apartment more for a couple than any more people, as it could be a bit snug.
Otherwise, a great find and Giulia was super responsive even we were checking in late at night.
