The apartment was exactly what it says on the advertisement. It's a small room (perfect for what I was looking for), close to the central station, next to a supermarket that opens from 7h to 23h and the fridge and microwave in the room are really helpful. Even there's no kitchen, clean dishes are available (and cleaned again for you) in a comfortable way so I didn't miss the kitchen.
Jan was also very kind and willing to help. Flexible and great.
I enjoyed my stay there. Thanks!
