Carsten is the greatest host I ever met. He is a very friendly, helpful, and humane person. I spend 2 months in his apartment and he was trying to help me with any kind of obstacles and difficulties I faced.
His advices helped me a lot during my relocation period.
The room and apartment are very nice, comfortable, and cozy. All the needed things are present. The location is quiet and close to the city center and metro station.
So, I can confidently recommend Carsten's apartment as the best choice.
