A really clean, central flat with everything you need for 6 people. Was just down the road from the subway and about two stops from the Centre. Simone was a fantastic and friendly host. She let us put our stuff in before she had finished cleaning so we weren't lugging it about all day, then gave us a tour of the flat and all the information about Berlin we needed. She was also available to text if we needed to ask her something during our stay. Would definitely recommend.
