We had a great time staying in Massimo's house. The place was clean and comfy. His house is conveniently located tucked away from the main tourist's hotspots. But there are still tourists outside in the square as the church next to Massi's house is famous for Vivaldi was baptised there. If you are arriving by water taxi the best place to drop off at Palazzo Cornoldi and walk up the alley way. There is a nice snack bar in the next alleyway Calle de la Pescaria you can get good cheap pizzas. We will definitely stay there again if we return to Venice.
