Apartment sharehire, Norwich?

Not a meet, but there's nowhere else to post this. Problem: I can't accommodate, and I need somewhere to meet in or near Norwich, for occasional afternoons or wends.

Anybody willing to share a flat or apartment rental? I haven't done much looking, but I think you can get something for £500-£600pcm. To get this to a reasonable price, I'd be looking to share with 2, 3, or 4 others. (Very) discreet clean couples preferred. I don't want to have to explain orgies to the neighbours or landlord.

Failing this, anyone willing to hire out en-suite rooms for an hour or two at a time?
