The apartment is clean and the beds are nice.
However, Stefan tried to ask for an absurd amount of money for a very minor damage (broken kitchen tongs). I really do not appreciate this. It feels like he is trying to make money of of the situation.
Also, the living room is way to smal for six people and so is the kitchen. The heating is not great either so be aware of that if your visiting in winter times.
Also the distance to the city center is quite far. With public transport it wil cost you at least one hour. With a car it might be better.
