OK, you are facing a glass door that is open, you will need to turn slightly to your right to exit this room, and to enter the next room which has a pool and seems to be a jacuzzi. You will need to walk towards the jacuzzi between the counter and the ladder that leads you to the pool. You are going to stand between the corner of the counter and the ladder to your left, slightly left, to have the jacuzzi in front of you. This is going to be your end.
