Well, now that you mention it I probably will have to smuggle her in a suitcase or box

the new flat is operated by the same tenant as my current one, but there's no reception area or security guards wandering around, only in the large gardens around the back
There's a pic of her sleeping in the images area
Thanks for all the advice everyone, I'm going to go off topic a bit and ask whether it's normal for a cat to only be eating half a tin of food a day? Harley's always been skinny & I've tried fattening her up but she only ever gets through half a tin. Do you think it may just be her breed?
