I've just came from a trip to italy. During my whole stay including 3 different hotels, hotel Paris in Mestre-Venice was the best. Its very close to the mestre railway station (just around 100-150 mt). The best thing staying in Mestre instead Venice is the affordable hotel prices of course. Venice is only 5 min with train and you can go there from mestre whenever you want. Train costs around 1 Euro. Hotel Paris is also pretty close to the airport shuttle service so you dont need to take taxi to go to shuttle station. It is a clean hotel for both young backpackers and adult couples. I will deffinatelly chose the same hotel for my next visit there.
