Shining in the Rain?

I'm off on holiday tomorrow.  We're going to go somewhere just outside St. Malo for a week.  This will give me ample opportunity to look around St. Malo, where a couple of chapters of Shining in the Sun take place.  I got my description of the place from guidebooks and Google street view, so I'm really interested to find out how accurate I've managed to be.  I really should have done the holiday before writing, rather than after!

I don't think there will be internet, so I'll be out of reach...
