Very calm Persian cat accustomed to indoor life

I'll try to explain quickly because I'm not used to writing announcements… This Persian cat has been with me for a long time and, frankly, he's incredibly calm. Most of the time he sleeps on the sofa or near the radiator, especially when it's cold. He likes it when someone gently strokes his fur, but he's not the type to run around everywhere. He eats his kibble without any problems and uses the litter box properly. I have to give him away because I'm moving to another city for work and no one in the family can really take care of him. I'd like him to find someone who likes calm cats.
