"Hmmmm. There's nothing to suggest that Diagon Alley is physically
in that location - the Leaky Cauldron might be a portal to it, but it
may actually be located elsewhere. A bit of portkeying to an isolated
location, perhaps?"

In PS Hagrid says 'Gringotts is hundreds of miles under London, see. Deep
under the Underground.'

Also when Harry asks about buying wizard things in London Hagrid replies
that you can 'If yer know where to go.'

These two points suggests that it is in London but it is possible that
no one knows about it transporting you elsewhere.
