Hello. You have not shown the map to which this question refers, which makes it impossible for your question to be answered accurately. However, I will try to help you in the best possible way.
First, it is important that the instructions are given in a clear, simple and direct way, allowing a good understanding of all the information. It is also important that both you and your friend know the concept of north, south, east and west, also known as cardinal points. This way, you must use these cardinal points to inform your friend the paths he must follow to get to your home. It is also important to show reference points that he will find along the way, which will make the instructions even more complete.
