I had a good-overall experience with this place and I would come back here for my next time in Venezia.
The location is excellent, to reach anywhere on foot! The house itself was as described, clean and tidy, warm, with all utilities.
One negative remark of our experience: when we arrived at the location, the keys were not in the secure box, which made us wait until the guaranteed check-in time, at 3pm, although we had arrived at 12. This aspect was unpleasant, being cold and very rainy outside.
