We had a amazing time at Janas place in the heart of Neukölln.
The apartment is quite spacious, which was an advantage in the winter, because our kids then had ample possibilities to play inside. Also there was plenty of toys to play with.
The area sprawls with nice places to hang out and eat, we really loved to breakfast at Greens Café, which serves really nice organic products, has a cozy play corner and a really nice staff.
We recommend Janas place to any families who wants to experience the Berlin vibe.
