Beautiful large house and close to the airport:
Don't take the bus since it costs a fortune - 8EUR for just 400meters (we did it and it was an expensive mistake).
Instead just walk about 20-25minutes from the terminal, we took the suitcases cart from the terminal and walked in the streets although people stared at us, it took us only 23 minutes.
And the hosts have a great information page of how to get easily in line no. 5 to Venice. just 9 minutes walking from the apartment
