Wibke’s flat was perfect. You can walk to other parts of the center city (about 2 miles) and can easily access the metro via Alexanderplatz. She provides site-seeing tips, coffee, tea, snacks, and let us leave our bags there until our train left. Wibke even let us do laundry and hung it up for us! She has another bedroom that she also rents out to Airbnb guests as well. I recommend staying with her.
