The Upper Room of the Passion Week

There's a big debate about the historicity or the tradition about this location. The Tuma David is in the same, kind of same building in the next side over and it's connected here. Some early sources refer to an early church of, of God or a kind of church of the apostles on Mount Zion in this general vicinity. And why is our church there? While the, the thinking goes that presumably it's where they started and it'sconnected to the room of the last supper.
