I guess, an English review will be more helpful than in German.
The appartment is amazing, very central and in a very vital part of town with great locations to eat nearby.
The apartment itaepf has a big sleeping room, a well-equipped kitchen, even a dining area to invite people is present and all that allows one to breathe and enjoy one's self.
The bathroom and shower are great too.
There is an interesting bookshelf with many interesting books.
The only thing I would remark is that the WIFI is a bit slow and qould not allow one to work on a bif amount of data.
But apart from that I can definitely recommend the apartment.
