The listing is misleading. The hotel is technically at 20 minutes by bus from Venice and the bus comes every hour or every hour and 20 minutes in the evenings, so not exactly as presented.
Also, in the morning on our checkout, at 9am, a cleaning lady knocked at the door, we said that we are still in and she opened the door to ask when we are checking out. Incredible! It never happened to us before. Not only we were asked about the checking out time, but someone getting into our room, shows a complete lack of discretion.
I wouldn't recommend this place. While they can't do much about the location, they can change the description to accurately reflect the time it takes to get to Venice and also to have a word with their staff regarding not entering rooms when guests are still in.
