Cornelia's apartment is just as it appears in the photos - wonderfully decorated, clean, and perfect for two people. Cornelia is incredibly responsive, and it was a breeze to coordinate our check-in and check-out. Should we have needed anything during our stay, I'm confident that she would have helped us out really quickly.
One thing that other reviews don't mention that I'd like to point out is that the street has quite a lot of nightlife on the weekends. We were warned by our taxi driver that the neighborhood gets rather loud and rowdy in the evenings. My suspicion is that there are a concentration of student bars nearby, which all look like a lot of fun! Perhaps it was a holiday or special event, but wow - the celebrations outside were incredible. Once we closed the windows, the apartment was fairly quiet and we had no trouble sleeping. Perhaps it was unique to the timing of our visit (early August) or a holiday, but it's definitely worth keeping in mind!
