I am an Egyptian student (Ph.D.) I have to appoint a room for about 2 or 3 months -it can be longer if the room is good enough- I have a work contract in MLU to perform my Ph.D., and the point is that I am arriving at 01-09-2022, this room can be waiting for me? I am a quiet and respectful person, this is my first time leaving Egypt, and of course, my first time going to Germany, I can't speak German, so it will be very nice from you (as a roommate) to give me some clues on how to live in Germany, how to speak, how to know the main routes, etc..
