We had a great stay in Ana and Guillaumes Neukölln apartment. There’s a lot of nice bars and coffee places at hand in the near vicinity. Bikes are for rent just around the corner and public transportation is also equally near. It’ a great home base as from which to explore the cool side of Berlin. Personally i like running, and the Tempelhofer Feld, was near enough to go running there.
The apartment itself is spacious and light and is equiped with all needed mod cons.
Communication was mostly by What’s app, but very quick and effective.
Very reasonable value for money in Berlin terms.
