The place is great. Very clean and comfortable, with everything you need. Alex was so kind that he even bought some stuff for our child we needed - like a high-chair and a baby-bath, so there was no problem for us staying there with a small kid. The location is just perfect. The neighborhood is quiet and cozy. Lots of great places to go with children like playgrounds and parks are in the walking distance. Getting to the city center is also very easy - the public transportation (tram) is nearby. There's also a FANTASTIC bakery next door. And by fantastic I mean heavenly great. It's like these buns and donuts arrive from heaven every morning. So if you're planning on visiting Berlin don't hesitate and book this place. You'll love it.
