Parwana runs the apartments she rents like a machine. You pick up your key from a lockbox any time of day, stay in a place with very good security, almost right next to the U-Bahn and S-Bahn. She was hands-off, but always available by text, email or phone call. Locally, the castle Charlottenburg is a quick, scenic walk. Don't be fooled by the seemingly out-of-the-way location; from this apartment, the whole of Berlin is at your fingertips.
