Brilliant apartment, has everything you could need!
I would recommend walking straight toward old Quebec city (a stones throw). I visited with my girlfriend and she was yelled at multiple times heading towards Saint-Roch Catholic Church. I visited 4 years ago and it was beautiful but unfortunately the area and more specifically that church has become a hot spot for drugs (saw multiple drug deals in broad daylight) and homeless to congregate, most were friendly but it doesn't make for a great vacation.
The host obviously has no control over who gathers in public areas. They were super responsive and had very clear instructions.
