I had the chance to have a chat with Saliha for a while and she was very friendly.
You'll have lots of privacy in the apartment. The room is big, comfortable and quiet, and the bathroom was also clean.
Location is great, at walking distance from Alexanderplatz, but don't miss Prenzlauer Berg, which is a very nice neighbourhood to wander around, with lots of bars, restaurants (I recommend Cafe Hilde for great breakfasts), interesting historical points such as Wasserturm. I recommend!
