We stayed at Myriam and Mathiss for a week with two young kids (2 and 4 years old). We had a really nice holiday. The kids loved the swimming pool and the dog and there were two babybeds and a children chair available. Berlin itself is a wonderful place for kids with a lot of activities like the Zoo, Lego Discovery World and a lot of playgrounds outside but also inside some coffeecorners. We love to visit Berlin again!
