Me and my sister had a wonderful time in Karsten's apartment in Mitte. His friend Sandra welcomed us late in the night and provided a complete explanation about the neighborhood and the city. The place is even more beautiful thank it looks in the pictures! Being conveniently located close to a underground station, the apartment is quite calm and perfect for hosting 2 people. I strongly recommend Karsten's place if you are looking for a true Berlinoise experience and a cozy place to stay.
