Hi Andy,
I would be very suspicious as the address does not exist. The postcode 13000 cannot be in Paris (a postcode in 13000 signifies an address in the Marseille region - 500 km from the capital...). To be in Paris, it would need a postcode beginning in 750 + the 2 digits of the relevant arrondissement/district.
However, there is a 'passage du champ a loup' in Paris in the 18th arrondissement (i.e. postcode 75018).
Of course, it could be a genuine error...
