Had a great stay at Katharina's place. It was clean, cozy, and very conveniently located. Just a couple of stops to the city center, or (as we did both days) a nice 35-minute walk. She left maps and tour books, it was clean, and easy to get to and into. She also answered all of our questions very quickly. Another bonus-- we were there when the temperatures were below zero, and it was really warm and comfortable inside! Definitely recommend, and would stay here again.
