My friend and I stayed at Cécile's place for 3 nights and I would definitely recommend it.
It is just as lovely as it looks in the photos and extremely spacious.
I really liked the location as it's on a cute street with lots of little shops, cafes and restaurants. There's also a great coffee shop directly below the apartment which we visited every morning.
It took us around 25 minutes to stroll to old Quebec and it was a couple of minutes to walk to a bus stop that took us to Montmorency Falls.
Cécile contacted me before our arrival and also after check in to make sure everything was okay, which it was.
All in all a great spot!
