Looking for long-term 2-room apartment / rooms in WG

Hi there!
We are 2 friends working in Berlin and we are looking for either a 2-room apartment or 2 available rooms in a WG to rent for long term.
We are Gio, a computer engineer, recently started a PhD at Charite university and Angelina, an architect working at Haas Architekten. We are both 28 years old (old schoolmates!) and we both come from Athens, Greece. We have also both lived in shared apartments in the past. We enjoy exploring Berlin, watching movies and planing trips, as well as having long relaxed conversations over food and drinks. :)
We both intend to stay in Berlin for the next few years and we are looking for a nice apartment to host us.
However, since the housing market in Berlin is tough, we'd also be interesting in mid-term rent (>6 months).
We would love to meet, view the house and chat in person!
