We stayed at Grazia's place for 2 nights and everything was ok. The flat is cosy, the location could not be more central, and Wifi is working well. The only thing that was unusual to us is the cleaning fee of 40EUR that is not included in the total price but demanded to be paid upon arrival. This information is included in the description of the offer, but it is still NOT the way it should be, as airbnb confirmed to me afterwards. No payments should be done beyond the official payment channel of airbnb for multiple reasons (e.g., safety of both parties), and that is what most airbnb customers are used to. It is also not really fair that the same fee is to be paid for cleaning, regardless whether you stay one week or one night. Make sure to pay attention to this issue before you book the place! Otherwise, Grazia was nice and even provided us with rubber boots since high water was expected in Venice during our stay.
