We have used BK for two moves, and to be honest have never had any issues with them, and they have been really, really helpful with sorting our paperwork, getting our needs from the landlord met and doing the work they say they would do. Most of the bad reviews here seem to me from people who lack basic common sense. IE, dont move into a flat you can\'t afford, dont move into a flat you feel pressured about, dont move in with people you dont like.
Black Katz have done what the remit of the company says it will do. We are very happy with the service.
