Having lived in Berlin for 8.5 years, I know it quite well. However, I was never atop one of those towers. A view I would like to partake of some day. I used to live over in Kreuzberg SO36 and Alt Treptow.
P-Berg - das Ökoschick Kiez. I have a very good friend living on Käthe-Niederkirchner-Str. She's been looking for a Spanish speaking tandem partner to do a swap for German. I believe she can engage comfortably with a conversational level. Beyond that, she's been living in Berlin for some 17 years and knows it very well, and is good fun to hang out with. I have a feeling the two of you might click. Would you be interested in connecting with her?
