I don't know whether Florence's nightlife is a hustle or not... I was not in the mood for it....
What I do know is that wandering around Florence at night was full of breathtaking sights like Ponte Vecchio with its lights mirroring at the Arno's waters.
The most beautiful memory of Florence itself, was the times I spent on Ponte Vecchio at dusk. Depending on the light and clouds, the reflections on the Arno River are something special. Pictures never do justice, and this holds true for mine. The best spot is either directly on the west side of the bridge in the middle, although everyone has the same idea. So, another spot is on the north side of the bridge just along the river to the west. Either way, you will be glad you came.
The shops remain open till night and as i have told you that there is as such no night life which is interesting so you so go for shopping alone or with your spouse at night. Especially the shops at ponte Vecchio look really beautiful.
Dress Code: Anything comfortable and warm.
just walk in the street in the night, take an aperitivo at Fusion Sushi Bar in Vicolo dell'Oro and just enjoy landscape
