We loved Andreas & Katja's apartment. It's very modern, light and spacious. The location is great. It was only a short walk to the tram and S-Bahn station. Within 10 minutes walk you'll find a large supermarket, playground, chemist and restaurants. We visited with our two children; the apartment is ideal for families - there are toys to play with and plenty of children's furniture, plates, cups etc. It is also quiet at night time. We would highly recommend staying here if you're visiting Berlin.
