Really nice place in a wonderful location. Clean and comfortable, with great service from Christian. I broke a glass by accident, and he said not to worry about it. I was also allowed to both check in and out at different times than standard. Super flexible and convenient. Everything was clean and as advertised.
The bathroom is small but very comfortable. The kitchenette has no oven, but the cooker works fine and I made lots of food and coffee and tea with no problems. You have to walk up three flights of stairs to get to the apartment, but it is a very cute building that apparently used to be a button factory. If you want to adjust the temperature, you have to figure out that there is a thermostat on the wall, and the individual radiators cannot be changed.
I can definitely recommend this place.
