We had a lovely stay of one month at Nicole's apartment. It is perfectly located, with restaurants, shops, groceries, and ice cream just steps away. It is walking distance from many museums and monuments, and close to several metro lines for easy transit to other locations. The kitchen is well equipped to prepare meals, the wifi and shower work well, and the bed is comfortable. We felt perfectly safe and cozy there.
As other reviewers have noted, there is noise at night from the nearby cafes and bars (although there was no noise from other apartments). However, once we closed the double-paned window on the street side, we weren't bothered by this at all. There is a pedestal fan for ventilation when the window is closed, and this worked well for us on even the hottest nights.
We would recommend Nicole's place to anyone who would enjoy this excellent location!
