It was indeed a nice private room, about 15 min walk from the train station Mestre. We had a nice warm welcome from Bruna who was well prepared to give us some suggestions for a walk in Venice and how to get there or where to eat. For food I definitely would suggest Osteria al Diplomatico nearby the appartment where you can order Italian bites at the bar and drink with locals. Staying outside Venice what the best choice for us.
