I stayed in this flat for 3 months and I enjoyed my stayed.
You cannot beat this location because it is close to everything. In general, it is surprisingly quiet for a place in the center especially at night since it is not on a street with a lot of bars and in the weekend because most buildings around are offices.
The only thing is since I stayed a while and needed to work inside, I could have used a slightly better internet connection at home but that is the only thing.
Otherwise, you get a big flat with a lot of light, a great view and a nice bathroom so I would definitely recommend it.
