Sophia's place is indeed a hidden gem in Charlottenburg. In fact, not only the location is superb, but the apartment is also beautifully decorated, and it has a cosy homely vibe to it. The room is quite large in size for a single person, and the kitchen has just everything you need. Supermarkets like Lidl and REWE are just around the corner. Additionally, both the S-Bahn and U-Bahn stations are within walking distance.
I was overwhelmed by Sophia's company as a host during my entire stay. She took me to so many bike tours to one of her favourite places, and we even tried different kitchens in Berlin. The stay at her place was my first experience with an Airbnb, and I am very pleased with it. I will highly recommend this place, especially to people coming to Germany for the first time.
