We had a great stay at Alex's place! It is 2 minutes walk to the Zeterre dock where you can use the waterbus to go anywhere in Venice.
The house itself is very beautiful and spacious big enough for a family. There are 3 bedrooms, the one upstairs has its own bathroom and a beautiful sky light in the bathroom. The other two bedrooms share the bathroom downstairs. There is TV in every bedroom, connected to wifi and they all worked perfectly.
It was very hot when we visited Venice so the great air-conditioning in the house was really a plus for us. There are great restaurants nearby and very easy to walk to all the major places from the house.
Overall, it was a great stay and we enjoyed it a lot. We would highly recommend it.
