Who allowed Jesus to use the upper room for the Last Supper?

Unfortunately, we are never given the name of the man who lets Jesus use his home for one of the most important meals in all of history. 

We know, from the accounts in Matthew, Mark, and Luke, that Jesus sends several of his disciples into the city to find a man. In Mark and Luke, the disciples would know this man because he would be carrying a jug of water. At the time, men did not carry water around. That was a woman's job. So it would have been out of place for the disciples to see a man carrying water. Thus, the man would likely have been easy to spot. They were to follow the man with the jug to his house, and then ask where the room to hold Passover was. 

In Matthew's Gospel, we get even less information. We just know that the disciples were to go find "a certain man" (Matthew 26:18). Then, when they found this random man, they were to ask him to use his house for Passover. 

This might be a man Jesus already knew and had made plans with or it may be an example of a miracle.
