I'm looking for a website that displays addresses in major European cities on a map.
I'm not looking for specific addresses, but for a a site in which I'll be able to type a certain address (street name and number), and get a map indicating the location of that address.I'm especially interested in sites that displays in such a way addresses in Rome, Florence, Paris, London and Amsterdam.
It's not important to me whether the site is in English or not, as long as it's obvious where to type the required address.
