There are many good sniping positions on this map. The first is a small room overlooking the garden and the front staircase. To get to this room either climb the ladder or go up the stairs. The second location is a small room that has a clear line of sight into the room mentioned above. To get to this room, go to the bottom of the map and climb up the staircase. You should be on a wooden porch that connects to the gardens. Turn left and you will be in the room.
