It's best to travel light here. The first acquaintance with the city will help to make a map of Venice, on which you will see the six central quarters of historical Venice and remote islands that are also recommended for visiting (Torcello, Murano, St. Lazarus Island, Burano and others).
Map of Venice with hotels will allow you to find suitable accommodation. If the central areas are too expensive for you, go to nearby areas, such as Mestre.
A detailed map of Venice will help you find the nearest airport, choose a route excursions and tell you how to get to the legendary cafe where Hemingway and Brodsky once drank coffee.
Trying to deal with the Venetian districts, tourists need to understand that geographically this city as a municipality includes the island and the mainland.
So, Venice includes the island lagoons of Lido, Murano, Burano, etc., as well as mainland areas, for example, Mestre. But we are more interested in the "old" Venice - its central island part, for which the main flow of tourists comes here.
So, the "classic" districts of Venice — is:
centre - Piazza San Marco, named after Saint Mark, the patron saint of the city;
San-Polo is another district in the center of Venice: there are many churches on its territory, including St. Paul, which gave the name to this part of the city;
Castello - the largest district of ancient Venice;
Cannaregio - in the northern part of the city;
Santa-Croce - you can park your car here;
Dorsoduro is the southern district of the city.
When deciding on which district to stay in Venice, consider the cost of accommodation and the concentration of attractions. For example, Cannaregio and Santa Croce are relatively affordable districts in Venice, where it is better to stay for those who don't mind longer walks to the main tourist sites and want to save money.
There are no specifically dangerous areas in Venice as the city has a very low crime rate. The most important thing is to follow basic safety rules: do not leave valuable items in your car and keep an eye on your wallet, especially in crowded areas.
