Katharina is a great person! She knows many things for Berlin. Besides, she helped me a lot during my stay in her place :) Everything in her apartment is perfect, large and comfortable room, clean toilet and kitchen. You can find everything you need near the apartment, supermarkets, bakery shops, restaurants are all around. Metro is just 1 min away. And you can reach Alexanderplatz in just few stations by metro!! Highly recommended for everyone who wants to experience Berlin!! Super!
