Cristina's appartement in Mestre is the best way to visit Venice I could find when travelling by car : there's a parking space for the car and it's about 50m from the bus stop that will take you to Venice for 1.5€/p/trip in about 15 min. With that, the appartment was really nice and clean, well equipped. We were greeted by Cristina who explained us all we needed to go to and visit the city. On our last day, we unfortunately had a bus/vaporetto strike, but could still easily reach Venice by train as the station is also very close. If we come back to continue our visit of Venice, we'll clearly try to take the same appartement again.
