Pros:
+ Fantastic location
+ Great washer and dryer
+ Apartment is as shown in photos
+ Good value for money compared with other available options in the same period
Cons (I stayed for a long period, these might not be a problem for short stays):
+ Very slow internet
+ Annoying and nosy neighbours
+ Humidity and mold problems mentioned in other comments do exist, but after the first couple of days opening up the windows it was ok
+ I had to work from home, the apartment is in the ground floor and it's a bit dark
+ Very basic decor, specially if you're planning on cooking (e.g. 2 spoons, 2 knifes)
