My place is located in the heart of Kreuzberg 36, Kottbusser Tor. Many bars, clubs, restaurants and shops are at walking distance, and you can reach the metro station in 2 minutes (two lines: U1 and U8).
The apartment is spacious, with big common areas, such as a balcony and a comfortable kitchen area. You would be sharing the apartment with 3 guys (English/Italian, German, Chilean) all in their late 20's and very nice.
My place is great for couples, solo adventurers and business travelers.
