My current address has no street name, just a house name and village name. Technically, there is a street name, but no-one uses it because it's the main street through the village.

I really don't see it as a problem: the local postman knows every house, and these days with GPS the postal code gets delivery drivers within a few yards without a problem. In fact, a post code and flat/house number or name is technically enough to identify any property.
