Everything was perfect since the beginning with Katja and the communication very easy. She made our arrival very convenient as we we're landing a bit late in Berlin. The apartment is charming and comfortable, ant the balcony is really enchanting, especially for the breakfast. It is also very well located in the heart of Prenzlauer Berg and near Mauerpark, where you can really feel the spirit of this city. The transportation was easy too, the tramway stop is just near the apartment. And there is so much bars and excellent restaurants in the neighborhood that the choice was embarrassing ! A very very good stay in definitive, and when we come back it will be at Katja's without hesitation.
