The place is right next to the train station venezia mestre, which makes is very easy to go to venezia. Train ticket is only 1.25€ but if you wanna stay out longer at night the last train is around 11pm.
The apartement was very clean. The only thing you should be aware of is that Lucia doesn't really speak english but still enough to give us the most important information. That's why it didn't bother us.
