The particular structure of Venice, by water and by foot, is hard to comprehend for people that do not often spend time there, and the restrooms can be hard to locate.
In order to facilitate the search, the service manager Veritas spa, has created the app Bagni Venezia, which can be downloaded for Android and iOS devices, and the website www.wctoilettevenezia.com where you can find all the news and useful information necessary to reach the restrooms in a short time.
In all the restrooms you can also ask for a free copy of a traditional paper map of all services.
