The flat was really clean, with plenty of space for my stuff, and Stefanie was very friendly and responsive all the time. You will be in a very convenient location, close to several cafes and shops, and well connected to other parts of town.
The flat is also quite warm, which I appreciated considering it was snowing outside. Both check-in and check-out went very smoothly.
I would go there again, my only tip is to upgrade the internet plan for guests who stay longer than a few days :)
