You're starting in a bathroom, looking at shower with glass doors. To the left is a door to leave the bathroom. Go through that all the way until you hit the longer hallway. You'll see what look like brown wood cabinets with metal handles in front of you. That's the hallway, you need to take a right down that hallway. Go up the stairs and toward the large white pillar that is made up of square stones. Veer to the left of that and go through the door to the outside. You're going to see a metal gate with vertical bars. Go right up to it, by the door handle and you are at your destination.
