We spent five nights on Franzi's apartment. We did not meet her in person, but she was available to answer all our questions on WhatsApp. She left the key at a little shop across the street. The apartment was clean, cozy, spacious and warm, with a well equiped kitchen. The wifi worked really well and Franzi left us a lot of recommendations of what to do in Berlin. The location was excelent, close to public transportation and to the city center. It was our first time on Airbnb and we couldn't have asked for a better place to be!
