Arne has a beautiful apartment in Berlin Mitte! Great location next to Rosenthaler Platz with lots of shops, restaurants, bars etc around. Balcony has view to the tv tower! I would love to come back in the summertime! The little bed room is nice and functional - had a trendy hotel feel :-).
We didn't see Arne that much as we were visiting friends in the city, but he seems like a really nice guy.
