Correct Italian Address? Help!?

I need to mail a check to this business in Florence Italy called Old Florence Leather Factory. I have what seems to be an address but i dont think it is the mailing address, here it is,
Piazza S. Croce, 14 (largo Bargellini, 1) Firenze .
If this is the correct address please tell me, Thanks

You have what seem to be two addresses.

In the online white pages there is a business called La Griffe at Largo Bargellini, 1 but nothing at Piazza S. Croce, 14. La Griffe is equivalent to "Brand Name" so it's possible this is what you are looking for as sometimes the name of a store is not the official business name which the phone number is listed under. (In touristed areas many stores get Italian sounding names and nobody worries too much about phone numbers as tourists don't generally call but happen upon streets).

I wish I had seen this earlier as I just got home from having dinner on Largo Bargellini and could have checked it out for you. It looks like the address you have is for a street corner or potentially for two adjacent places. Largo Bargellini is an off shoot of Piazza Santa Croce. Do you have a phone number for this place...it might be easier to do a reverse search to get the address that way.

If the info you have is correct you would write the address like this (I've added the proper zip code):

Old Florence Leather Factory
Piazza S. Croce, 14
50122 Firenze
Italy

or

Old Florence Leather Factory,
Largo Bargellini, 1
50122 Firenze
Italy.

If you have the phone number let me know and I might be able to help you out better.

there is no zip code!!but if you write on italy it's correct!

This sounds like a reasonable address. Largo Bargellini is at Piazza Santa Croce. I know there is a restaurant and some leather shops in that area. I am not specifically familiar with the Old Florence Leather Factory, but the convent has a leather school. You'll also need the equivalent to the zip code: 50122.
