Virginie's airbnb was amazing! I stayed there for over 2 months and had a great time. It's right in the hippest part of Neukölln - lots of bars, restaurants and cafes right around the corner. The apartment itself is nicely set up with everything you might need, and Virginie is super responsive if there are any problems. The apartment is a bit small, but it has a lovely minimalist designed feel. Because it's in the back building, its also really quiet which is great.
