Who’d be a postman in Venice?
On the plus side there doesn’t seem to be a problem with being attacked by dogs on your way up the garden path, but the downside…
There is no numbering of properties by street. Within each of the six sestiere that make up the city the properties are numbered consecutively starting in one “corner” of the district and working across to the opposite “corner”. Given the shapes of the districts, and that Dorsoduro incorporates an entirely separate island, the process doesn’t always seem to follow logic. House numbers can run into tens of thousands.
What’s more, each number is painted above the door in the same way, which must have looked fine when the paint was fresh, but in Italy paint is often left to peel and fade.
Buona fortuna postino!
