My GF and her parents will go to Venice in June. They will arrive from northern Italy by car. Of course, they can't take the car to their hotel which is in the historic center of Venice.

What is the best, safe parking option for a car (Volvo XC 90) that gives easy access to Vaporetto lines 1 and 82 (82 is correct, 2 in the title was a typo)? They will stay for four nights.

Here is the description of how to get to their hotel:
Domus Ciliota is situated in the historical centre of Venice, a few minutes walk from St. Marck's Square, between Campo San Samuele, Palazzo Grassi and Campo Santo Stefano.
Domus Ciliota can be easily reached from Piazzale Roma and the Railway Station by the vaporetto n°1 (stop at Sant Angelo),or the vaporetto n° 2 (stop at San Samuele).

Address is:
Calle delle Muneghe - S. Marco, 2976

Thanks,
