This website: http://www.londonbaseapartment.com/index.html provides imaginary apartments in London, along with an imaginary driver to get you from airport. They ask for an advance payment of deposit (like you could brake anything when you're not there yet) through Western Union. Obviously once the money get to them no one answers any mails or telephones.

The firm they claim to represent on the website, Apartment Rentals UK Limited is dissolved since 2007, I looked it up. The other one, Mania Estates Ltd doesn't even exist. The only real person around is probably Kim Howells, "the owner", because I assume that to get the money from Western Union you need an ID. I hope they won't find any other "customers"..
Take care.
