I found this strange case of place mismatch on an object tagged with addr: place. The address of this point is:
city: Recanati
street/place: Frazione Montefiore
housenumber: 23
This address gives no result but I found out that there are two results for this one:
city: Recanati
street/place: Contrada Mattonata
housenumber: 23
the right one is here:
but the other result points to the previous one.
Here is a map in case anyone wants to try to understand what happened.
