Maria's apartment is perfect for 4 persons. The kitchen has everything you need, it just could need some more accessories to feel more home - because the flat is really huge, which is not a disadvantage at all. :)
Unfortunately, during my stay there was a daily construction above me (announced!) and the flat has a huge issue with mold. Additionally, you need to know that you have to pay approx 450 € additional power fee (in winter!) when you want to have a well tempered flat (= using the provided heating).
But overall a nice space in a nice location - not directly inside the touristic world. Check-in and communication was also perfect.
