We were a mixed group of 8 people, including 2 kids, and this apartment was just great for us. It is a very nice apartment with enough space for even bigger groups, including comfortable beds, beautiful and cosy common space, big dinner table, and everything you may need for cooking. We stayed there in winter and the heating was really good, the apartment was always warm. We enjoyed having breakfasts and dinners all together and chilling at the common space without feeling crowded, it was perfect. There were also a lot of toys for the kids to keep them entertained. The neighborhood was safe and quiet, although it was a little bit far from the tourist attractions, Berlin's great transportation network took us anywhere we wanted, we just needed to do a few connections. The U-bahn was about 10 minutes walk, but the bus stop was closer. We really enjoyed our stay, definitely recommend for especially large groups and families.
