The apartment is good, enough place for 7 . There are 2 rooms , one of them get it is own bathroom, the children stayed on the sofa in the living room , and one extra bed has been installed. It was clean, and manageable for a large family.
Regarding the noise, it was ok, except one night, due to a very noisy neighbor. The rooms placed on the back are quiet, the living room is placed on the street side , so it is more noisy.
The location is Camden town station, so very easy to connect with subway or bus. By example, 40 min on bus to join Westminster.
