Italo was very friendly and helpful! He came to pick us up from the port near his house and gave us a map of the city with recommendations of where to eat.
Upon arrival, he took a picture of our ID cards and we had to pay 30 euro tourist tax (2 adults + 1 kid for 3 days).
The apartment is alright. The rooms can get quite hot at night so a second fan and something against the mosquitos would be nice, and it would also be convenient for light travelers if there is body wash and shampoo available.
The apartment is not located in the center, but there is a waterbus stop nearby, and Venice is small so everything is reachable within let's say a 30-minutes walk.
We enjoyed our time there - thanks!
