Advantages:
The flat is near to main touristic places, although it is not walking distance. Cheerful Wolfram. Flat fully equipped and functional. Restaurants and some city life nearby.
Disadvantages:
If you are ok with living in the basement, it should be fine for you. The toilet door is in fact a semi-transparent curtain, and the ventilation is not enough to clean smells.
A fat cockroach once detected (and annihilated).

All in all for this money it can be better.
