Marcelle is a top notch host, who was ready to be contacted at any moment and even offered us the option of alate checkout since she had no-one booked the day after we left. The location of her flat - in a historic Carnareggio building -- is fantastic; calm and picturesque by day, eery and beautiful by night. I would recommend staying here particularly in winter, and savouring walks through the narrow streets that line the canals, either in the direction of San Marco, or the Jewish Ghetto.
