Amazing place. The room is fantastic and Katia is very Kindly. The B&B is placed in the center of Mestre. Very easy to arrive from Mestre Train Station. There are several buses to the center of venice (it takes 10 minutes, 1.50 euros, Bus 4) 5 minutes walking from the Room.
And you can easyly go to the AirPort from the train Station (takes 20 minutes, bus number 15, 8 euros)
Great stay.
