I don't know if he stayed with a king, but most famous composers usually preformed for people with a higher rank in class, such as a king, or govenor or people of that sort.
King Claudius
Mozart's 5th opera was Mithridates, King of Pontus.
I just recently visited Venice. I stayed at Hotel Mercurio, and had a room which looked over the Canal of Barcaroli. Directly outside of my window, was the building where Wolfgang Amadeus Mozart stayed. There is a message written in marble right on the building indicating such. The gondolas would come by and the gondoliers would tell their passengers that it was the building where he stayed. So, the answer to your question is the Canal of Barcaroli.
Mozart wrote most of his music for the king, because Mozart that was Mozart's job. Often for himself (he was a very fine pianist) although he also wrote commissions for other pianists.
That depends entirely on which king is in question.
Mozart because he wrote the most works.
