As soon as I saw the mirror selfie of Christian in his airbnb photos of his apartment I knew he was my guy.
After living in his apartment for 4 months, I can safely say Christian is one of the most easygoing, cool, and kindhearted dudes I've ever met. He checked up on me often and offered a lot of guidance for me in Berlin.
Aside from his personality, the apartment itself is spectacular. The floors are beautiful, the bathroom is great, and the shower has powerful pressure. I really liked staying there. The rooms are spacious too. It feels very newly renovated.
Location wise, Kreuzberg is a great spot in Berlin as well. It's loaded with cafes, bars, shops and all that. It's also close to the club area as well which is a perk too. The apartment is in a great spot in Kreuzberg, a half block away from a great yoga studio, and 2 blocks away from a grocery store / super market. There are also a number of late night food options around too.
I couldn't recommend this place more. I stayed there for 4 months and I didn't have 1 issue.
