Looking for one room flat or shared room (for a couple)

Hi, we are an italian couple, 36 and 32 years old working both in cinematography in Rome.
We are searching for a one room flat or one shared room in Neukolln, friedrichshain, Kreuzberg or Tempelhof (we've friends nearby) and we'd like to "test drive" this amazing city for two months.
With us there's a sweet and well educated dog named Gusto; she's 5 years old and she never gave any kind of trouble.
We're two serious guys and at the same time we like to enjoy and play life! We can give you all the guarantees and documents you need. We're planning studying german, but at the moment we've no problems speaking english, spanish, and obviously italian :)
Important, in case you're interested, we can be flexible about our arrival and departure dates.
So, we wait for your news and Danke schön!
