Very old building so it has charm and challenges. Too much stuff left there in the apartment, almost like a cottage where old things go to die. But it was spacious and comfortable, so we were really quite satisfied. Warning - after a long day of travel, and little German, asking the adjacent restaurants to let you into the front courtyard is not fun when they have no idea what you want. Both places had basic English speakers but had no idea why we wanted their help to get inside the courtyard. Eventually we figured it out with some awkwardness. Next time I’d come prepared with a translated explanation.
