Do not use this company. Their letting agents are friendly and they have a decent amount of stock but pressure people from the outset to accept houses without any time to look it over. My friends and I took a house in Camden that had been refurbished by Black Katz for a non resident landlord. When we moved in their was a long list of items still to be finished - installing blinds, cleaning paint of counters, servicing the heating, the washing machine and the cooker were faulty - we took a list and sent it in to the "maintenance team" It has taken 3 months and plenty of emails and phone calls to get some of the work done, the rest is still outstanding. They also changed the locks to the house on Christmas eve without telling us because an unannounced maintenance person suspected the door had been tampered with - Never contacted us and then when we had to use a locksmith to get in on Christmas day they refused to refund the charge.
