I really liked all elements of the apartment, but two things should be emphasized. First, the apartment is extremely conveniently located. 3 minutes walk to a decent grocery store, 3 minutes walk to the nearest bus station, and 7 minutes walk to the nearest metro station. Second, this apartment is very quiet. I stayed there during my business trip, and I really appreciated the silence in the evening.
Two downsides: wifi was sometimes a bit weak and the place is not the easiest to find when you arrive. But they are both pretty okay. Nothing to criticize otherwise.
