Solution for Safe Lock
How my friend and I worked out the safe:
We used the compass to orientate ourselves. Then we placed the compass on top of the safe to make the puzzle a bit easier. After that we needed to figure out which building we were in.
We did this based off of some notes found in the room and one of the directional cues given in the red, yellow, and white instructions.
I’m sure seeing the church outside of the window would also be helpful (as noted by Caleeloo), but we didn’t notice this in our play through.
After that we followed the red, yellow, and white instructions while thinking of the map the way the compass faced.
