We stayed almost a whole month at Christoph's place and really enjoyed our every day there. The place has just been freshly renovated, has a great modern touch and it's equipped with everything you need. It is also tucked away in the back house of the building, so during the hot Berlin summer months, it was kept nice and cool. Christoph is also a great host; always available and very responsive. All in all, a great spot to discover Berlin from.
