Lovely apartment with a great location and best I've slept in in a long time!
The communication was a bit strange, though. After booking, Christoph asked me to send him my credit card number, CVV, and expiration dates for a deposit that hadn't been mentioned in the booking, outside of AirBnB. He also asked me for a picture of everyone's ID's, which also seemed odd given that I've booked other AirbnB's in Germany and no one asked me for this.
