No experience of the WG. But I am familiar with the flat she's using. Used to see a regular in there, and I expect she's rented it out while she's away.
You may have trouble finding the place. It's right at the front of the road to your right as you walk/drive in, just up a short flight of stairs, almost overlooking a bus stop. I'm telling you this, so you're not wandering about the cul de sac, confused, with a semi in your trousers, fphoning and texting and looking exactly like a bloke trying to visit a prostitute but doesn't know where he's going.
Also, the flat is tiny. You'll be fucking her about three feet away from the front door.
Enjoy.
