Pros: although the building is old, the apartment is pretty spacious. The hosts are vesy helpful. He met us at the gate downstairs upon checkin and showed us around the apartment and even gave us very useful local tips: where to eat, what to do, where to go, which is very nice. We asked him for mosquitoes spray on the second day and was provided with one immediately.
Cons: there were mosquitoes, which we think is the part and parcel of Venice - the mozzies are massive. There was barely enough toilet paper (given we only stayed for 2 days), and there was no washing machine in the apartment.
