she's not lazy - you make her feel safe! its actually quite common for kittens (and less so but adult cats too) to pee on their peoples bed. it smells of you, particulaly when you are in it so its a place where she feels safe. the move has probably unnerved her which is why she is doing it more now than before. she should stop doing it once she has adjusted to the move and feels safe in the bedsit, although do get her vet checked just in case there is a medical issue.
my kitten did the same when she was younger, she was feral born so was a little nervous and very bonded to us. without realising it you are probably showing signs that its not a good idea to pee on the bed, i know whenever we felt the warm wet sensation we lept out of bed and then did duvet swopping, which was not what my cat broo wanted as she was hoping to just settle down into a nice bed!
I've attached Yorkhire Cat Rescue's guide for inappropiate toiletting in case its of use to you.
