The flat itself is great, 3 bedrooms, 2 bathrooms, everything you need in terms of comfort. it was spotless when we arrived.
The location is not ideal, very quiet and not the best connections in terms of transportation. we knew it so it was ok for us, but if you want to be in the beating center of berlin, look somewhere else.
I just take out one star because apart from the very moment we arrived i was unable to reach Kathrin on the phone number provided, but orherwise she was always very reactive on airbnb messaging.
