I'll do my best to give an objective review even though Claudia is probably leaving a very unfair one for us.
The flat is okay, very spacious and well equipped. Air conditioning (which is charged separately) is not suited for the size of the aparment. The a/c units are very noisy and can barely cool down the rooms. The kitchen, living room and bathrooms were so hot that we had to stay in our rooms while at the flat. I wouldn't recommend to stay here during summer/winter months.
After spending some lovely days in Venice, we unfortunately left with a bitter taste. After check-out Claudia contacted me complaining about some alleged damage to a toilet lid and an armchair she has in the bathroom (?), acussing us of also "fleeing" the flat, even though we had informed the person in charge that we had an early flight and would be leaving at 7am. I was very surprised by all this after seeing her positive reviews, but I guess you never know. I would recommend guests to take extra care and take pictures of any damage you find during your stay.
