Despite her BA1 postcode, she actually is way out in the Boondocks. It's a good 45 minutes from the center of Bath by car.
Confirmed BRBRBR, it's a reasonable drive, depending which part of Bath you're in.
I think she does this to protect her privacy due to her actual location, which seems to vary.
Just to flag (again) that mobile coverage may be a challenge when you reach the postcode she gives you, depending on your network.
