Staying at Dogmar's was awesome! She was extremely helpful. When I arrived she let me borrow a prepaid phone and bus pass. I was introduced to one of her closest friends right away. :) I felt welcomed in her house and more like a friend than just a guest. I recommend staying with Dogmar. Her and her friends were also more than happy to teach me about German culture when I asked questions.There is a train in 10 minute walking distance that will take you all over Berlin. There is also a grocery store if you need food right by the train station. Happy Travels!
