We spent nice 4 days in Stockholm, in the apartment.
The apartment was 90% fit to the description. As it was written by others as well, there is huge construction work just in front of the building and as it looks like this will not ends in the coming 1 year.
But if you go for sightseeing during daytime, this will not be heavily disturbing as the work is over after business hours.
Indeed there is a pub below, but that you shold accept if you are in the middle of the city.
In general I recommend you to stay in the apartment.
