If it's only for a week I probably would not bring him to your house. Now if it was a month then I might consider it.
IMO, it could just cause a lot of unnecessary to one or both cats. It takes longer than a week (usually) to introduce cats to each other.

But if you are really set on it then you would just need to take it slow and see how it goes. Put Prince in a carrier and let Simon sniff at him for a while. Then you could put Simon in a carrier and let Prince sniff at him.
I am doing it differently in my house. I have a spare bedroom that I will put the newbie in with the door closed. I will eventually open the door with a baby gate, then without the gate (all well supervised). But this is for a new cat that will be a permanent resident in my house. Even when I was watching my friends cat for 4 months he only came out of the bedroom when I was home and could watch him. We did put up the baby gate during the day so he wasn't all shut up in the room the entire day.
