Most of the stuff she writes is made-up nonsense - some of it possibly has a grounding in truth but ends up so embellished.
I think she has mental health issues. She doesn't seem to be able to manage finances at all. Everyone knows that it is completely ludicrous to spend 59K of your own money on doing up a rental property which does not belong to you.
The landlady probably thought great, she's done the place up, I can sell it now and get more money for it.
I live in Austria. Rental properties here do not have kitchens as standard. So that means when you move somewhere you might be lucky and have a kitchen included but more often than not there won't be a kitchen. The previous renters might agree to let you buy their kitchen from them or they might take it with them, which is their right. If they do, you need to get your own kitchen installed which is then yours. The deposits are also very high - three months rent.
However, rentals are much more secure - long-term lets, initially of 3 years are standard with this then rolling over to be permanent. Very difficult to get a short-term let. If you want to move out before the 3 years are up you have to sublet to someone else.
But what this means is that your home is your home. A landlord does not have the right to say you can't have pets. You can decorate etc.
