We also had a big issue with the noise, but I think it was just an unlucky period for us to arrive at the location.
There were repairs being done to the roof (or some type of work done), and the apartment was on the last floor. This meant that in the weekdays, there was an infernal noise in the apartment, starting early morning.
At night and in the weekend, it was OK, even tough the Overground rail is across the street.
I will say that I loved the blinds, which made the house pitch black at night.
