Looking for an apartment for 3-4 persons!!!!

Hello I am a mexican graduated and I am helping my friend to find a furnished apartment available for 3-4 persons. One year ago I lived in Dortmund and really liked the city but nowadays it is very difficult to find a place to live and I offered to help my friend. If anyone could offer us a good deal for 4 months would be great to find a nice place with bus and u-bahn stations, also with any Rewe or supermarket close , dusseldorf, mitten, Lütgendortmund, por another área is fine. My friend is also mexican speaks and understands perfect german and will be studying 4 months in dortmund it will be living with other two or three students . Apartment must include furnish , complete bathroom, complete kitchen, if its possible some dishes, internet is very important , desks, chairs, if its possible TV .
