Andreas' apartment it's really a perfect place to stay for a visit to Berlin. It is clean, comfortable, beautifully furnished, and much bigger than it looks in the pictures. The location is great, in the middle of the action but perfectly quiet. There's a streetcar stop in front of the house which takes your straight to Alexanderplatz. The Schönhauser Alee U-bahn, which takes you anywhere in the city is a five minute walk away. The shops and restaurants of Kolwitzkietz are a block away, but it situated on a real street outside the tourist ghetto. Communication is almost instant, and Andreas was extremely helpful about everything. I couldn't recommend his place more highly.
