British vs American Usage
Differences
As a US place name, it has no direct British equivalent. British speakers would simply treat it as a foreign proper noun. The structure 'Valley' as part of a place name is common in both varieties, but 'Castro' as a surname-derived place name is more typical of US and Hispanic-influenced toponymy.
Connotations
For Americans, especially Californians, it connotes a specific Bay Area suburb. For British speakers, it likely has little to no specific connotation beyond being an American place name, potentially associated with the Castro district in San Francisco or the surname Castro.
Frequency
Virtually never used in a British context unless discussing specific US geography.
