Overall the place was nice. Mestre is about 20 mins away from Venice island. If you don’t mind staying around the air bnb rather than island there’s lots to do in Mestre . If you plan to spend lots of time on the island itself it may be best to get a 2-7 day transit pass that will include the surrounding islands and boats; this can go up to 60eu. The buses aren’t always frequent so you have to plan your daily trips accordingly. Google maps did a fairly good job at directing us to which bus/boat we would need. The buses are very packed so you have to make sure you get on (sometimes this means squishing) and tap your ticket to validate that you paid. It may seem like no one pays and you can get away with it but on our last day there we saw ticket inspectors checking everyone’s to see if they had a ticket. It’s 3.00eu one way if you buy on the bus. 1.50eu one way if you buy it at the ticket booth or machine.
