Place is perfectly as described. Apartment is fine, kinda hipstery, but that's Berlin, and I guess most will like it. The most important thing is that everything is as described and as in the pictures. Sarah and Joseph were rapid in responding and cool to work with.
As was said in the description, the entrance and the building itself are not so nice to look at. There's something wrong with Berlin regarding cleanliness.. But you forget that once you're inside since Sarah keeps it perfect.
