If your employer is bringing you in on single status, make sure they will take care of your accomodation. Usually the company will sign the lease, then whoever lives in the flat is the company's choice.

Security shouldn't be an issue anyway, but it might be better for you to have a female roommate.

Too bad about the legality issue - having seen your picture, I'm sure there would be no shortage of young men willing to share their flat with you ;o)
