You will start by facing a doorway. Take a step forward don't go in. Turn around and you will see a blue door ahead of you. Make your way towards the blue door and exit the house through that door and take a step outside. Now turn left you will see a little corner with a hose. Walk towards that and take one more step forward towards the windows on the left. Once you are facing a large stone thing or wall and the left are the windows then you're done.
