My place is close to Schiller Burger and Engels Café. Right outside Karl-Marx Ubahn station and close to Weserstrasse & less than 10 minutes from Kreuzberg. Many bars, cafes etc. are within walking distance.
I'll be renting my room while I'm traveling so I will not be here. I have a flatmate though who will be here (in a separate room) during your stay. She's a Swedish girl, age 22, studying fashion. Very friendly and nice:)
This is a 63 sqm apartment with wooden floors and high ceilings.
