sublet with 2 small rooms/studio apartment for 2 friends fr 19/9

A good friend and I who recently moved to Berlin from London are looking for a furnished sublet for 2-3 months from September 19th. Preferably in Kreuzberg, Friedrichshain, Neukölln or Mitte but open to other areas also. We would like to share a studio apartment or an apartment with 2 small rooms and 2 seperate beds are needed. Alternatively, 2 small rooms in a sharehouse would be great too. We are both friendly, responsible, reliable and easygoing people who work in the creative industry and we are both in our late 20s and non smokers. Rent inclusive not to be more than 500 a month for the studio/2 rooms. Thanks and looking forward to hearing from you :)
