I took one of Bernhards Rooms in the basement for a month at a relatively good price and honestly, it was far better than expected. The basement had a large living room and a large shared, but definitely clean bathroom. Bernhard and Olga are both super good hosts, very friendly and welcoming. They provided me with more than what i needed and above all, were always reachable. As I was totally new to the city, all questions and clarifications were answered very quickly. Bernhard's other guests are friendly and welcoming too. Even the neighbourhood's lovely with accessible supermarkets / gas stations across the street.
I would surely recommend a stay at Bernhard's, if its not full already...
