Apart from the contact number for Alberto not working in England, contact on arrival was very welcoming and straight forward. We arrived by bus from the airport, but I suggest you use the boat on the way home .
The apartment was in a perfect location very central but also very calm and relaxing.
Venice is remarkably easy to navigate, make sure to visit some of the other islands.
If you go on a gondola, take one from a side canal as the Grand canal is extremely busy. Use the vaporetto boats to get around, you can get a day pass which does last 24yrs.
The apartment is lovely, but do take mosquito repellent with you, even in October.
