Overall our stay was nice. The apartment is very small but warm. It's very near to a metro station, the main street and many supermarkets. If you want to walk to the city center you'll need at least half an hour.
The apartment was quite clean, the only issue was that the bed was missing the fitted sheet. The kitchen is tiny, just for breakfast or noodles.
Karin was very quick to reply and she was very flexible with our arrival and living suitcases in the apartment, we really appreciated it.
