The location of Catherina's apartment is perfect - lots of great restaurants right outside the door and very close to the metro. The apartment itself was clean and well stocked, and Catherina was very accommodating. We got there around noon on our first day and left around 6pm on our last day, and she was happy to let us use the apartment the whole time. If there had been someone checking in on our last day, she would have kept our bags in her own apartment so we wouldn't have to worry about them.
