Looking for a room in sharedflat or a full flat

Hello! i am from Italy and i'm currently in Juelich.
I had started to work at the forschungszentrum in Julich as a PhD from the 1st of september and i'm looking to rent a room or a complete flat (in this case i could spend even 600 euros).
I am unmarried, no children and no pets.
I already had experience living in a rented apartment (3 years).
I have a car with me and plan to buy a bike.
I would need the room from the 12 september.
But before i would like to see the apartment, i'm available each working day after 6 pm and in the weekend the whole days, let me know if there is any spot available to arrange a meeting.
If you need any further information let me know and i will respond as soon as possible.
I do not speak German (still i'm planning to learn it), only English. Hope this will not be a problem.
Thanks for the attention
Cheers,

Giorgio Silvi
