Christian has a beautiful central apartment. I personally didn't stay with him as I live in Berlin I booked the room for my father who is 60 years old. He was made to feel very welcome by Christian and he was very comfortable during his stay.
The apartment is in the heart of Fshain and is close to bars and restaurants. It is clean and nicely laid out.
Thank you Christian for taking my father and making him feel welcome and have a great Berlin experience:)
