Florence's Terrazza con vista project is back for its third edition. Numerous rooftop terraces with panoramic views of Florence are open for the public until the end of September, either for dinner or an aperitivo, or simply to enjoy the view. This year there is also a photography competition, to be taken with cameras or Instagram. Participants can also submit short videos, and the prize is a stay in one of the participating hotels.
