Karin's apartment is located conveniently. You can use the subway to be in less than 15 minutes in the city center.
She informed me that it was currently a bit messy due to her moving-out .
Nonetheless, the apartment was not super clean (bathtub, and majority of sinks clogged - I unclogged them myself). Similarly for the kitchen which was always messy even if you try to clean it, it won't last more than a day.
Otherwise, the apartment is sufficient by itself if you search for a place to sleep.
