Our time at Katharina's apartment was wonderful! It is very spacious and the aircon and wifi worked like a charm. The location is great and only a short walk to the 1st district - we didn't need to take public transport once! We managed to cook some meals in the kitchen, however some of the essentials like dishwashing liquid were insufficient. We got the washing machine to work however did not have the same luck with the dryer. Katharina was very helpful and welcoming when we arrived, and responsive to our messages over the duration of our stay.
