Overall we enjoyed our stay in the apartment, it is spacious, and in a great location off the main tourist track but still very convenient for walking everywhere as well as very close to the vaporetto stop. All the rooms overlook a quiet and green courtyard. The apartment seems like a classic old Venetian one.
Having said that it is old and seems as though some maintenance is needed. The biggest issue was the master bed mattresses were very hard and uncomfortable. Other beds were fine. Minor issues were shower not draining well, fridge not very cold (but our food and milk was ok for the short time we were there), there is some peeling paint, and no soap was left for us. I did not contact the owners about the soap so maybe they would have sent some if I asked. Wifi worked well so kids were happy.
