In the center of Budapest, I bought a room with a treasury and a rooftop, where you can see the whole of Pest. After visiting the church, there is an elevator outside, and then there is a bathroom. First take the elevator to the rooftop to see the view, then go back to the bathroom. There is a staircase next to the bathroom, with an arrow pointing to the treasury. There is the hand of the first king in the church.
