We are standing on Calle del Forner in Castello looking towards Ponte de l'Olio on Rio del Fontego dei Tedeschi. This is one of the few spots in the city where three sestieri meet. From here we can see San Marco on the left and Cannaregio on the right. Ponte de l'Olio is even more special, from there one can see four sestieri: Castello, San Marco, Cannaregio and San Polo.
