Ka's flat is like our second home! We rented her flat for 1 whole month and we absolutely loved it, the flat is very cozy, she was living there so it's not just an empty place for people to rent the place, it has everything there, we have a 2 years old, he loved running around in the flat and he is so happy there, nice and bright flat with a cute bath!
And the area, we love the playgrounds around the area and love the neighbourhood, plenty of cafes and restaurants, if we would ever going back to Berlin, I'll definitely contact Ka again, she is super easy to reach and very flexible too
