We stayed at the apartment for a longer period, since we are moving to Berlin and it was a very good experience indeed. We had some hiccups with the internet, but our host did everything in his power and did not rest until the matter was solved. I can vouch for his availability and effort to make our stay as pleasant as possible.
The apartment is very well-located, near bars, restaurants and reasonably close to metro and tram stations that can take you anywhere in the city. The neighborhood is alive and young all the time. All in all, I can only say positive things about our stay.
