Philipp's apartment was a great place to stay. It is exactly as advertised in a great neighborhood with easy access to the U4 and the rest of the city. The decorations, cleanliness, and rustic feel were hard to beat. He does mention that you have to be 'adventurous' which I think was in reference to a very clean, but funny access to the bathroom. Still, my girlfriend and I enjoyed the place immensely and we were grateful for the apartment as the city was boiling hot outside, but the apartment was incredibly cool inside.
