Rue St Denis is quite rough, with prostitutes/sex clubs and lots of dodgy people about. WE had an altercation with a nasty man from the sex shop next to our graffiti covered front door, as I had taken a photograph from across the road and he was very annoyed and quite abusive.
It’s very central, but maybe more ideal for young people who can tolerate the grittiness of the neighbourhood.
The neighbours above us were terribly noisy and kept us awake most nights.
The apartment itself is very small but tastefully decorated. Beware the four flights of stairs- no lift!
