Birgit was very welcoming.
Her flat is clean and our room was large. It's up several flights of stairs with no lift, so be prepared to exercise@
Her flat is in a great location - within walking distance of lovely restaurants, cafes and shops in the hip Kreuzberg district and a stone's throw from the underground (U-bahn) and overground (S-bahn).
You can hear the rumble of the S-bahn, so light sleepers are strongly advised to bring earplugs.
