Could you speak to the landlord direct and explain the situation. My house was no pets, but I asked the landlords permission to adopt my girls and it was fine. I signed a letter saying I’d make good any damage they did.
Work out plenty of high up sunny roosting spots, preferably with views so that your cat can plot mayhem in the outside world. Most of the fun for cats is in the plotting. Make time to play with your cat and give him/her the chance to play with stuff. Even the old and infirm cats like a bit of gentle murdering of toys etc.
Actually I'm going to have to take the prisoner cell block H type place as the third apparently had nightmare tenants previously and would need a lot of reassurance and i don't have the time to sort it out.
I can't believe I'm making housing decisions based on the cat
If it's any consolation, I'd do the same. I'm thinking of moving to a small town from a rural area, but the thought of taking my country cat to a busier area is putting me off! Hope you'll both settle in well.
