Airbnb is also worth checking if the wg is happy to visit an apartment. Possibly more discreet than a hotel depending where you end up.
I have used mercure London Bridge also via 9-5.com£60 odd for a daytime booking, cash paid, not an eyebrow raised
Very helpful thanks chaps. I was standing by to book a few hours for a meet today, but the girl wasn't firm enough with the comms. Not going to commit to renting a room and risk her being a no show... I can stay at home and wank for free But I'm going to use these tips next week I hope and report back.Cheers
