PlaceFinder expects to see addresses in postal address order. For Spain, this is Street, House, Postal Code, City, Country. Do not include any non-address information, such as business or personal names. The following query should return the desired results: http://where.yahooapis.com/geocode?locatio...&appid=[myidapi]&flags=P
Please note that full name of the city is Sant Cugat del Vallès, and that we use the Catalan variant of the street name, carrer de Villa. Since PlaceFinder is a global geocoder, it is best to include country in the query.
