Jean-Felix’s place is great for exploring the city, Old Quebec and Petit Champlain are within walking distance, even with winter weather, and there are lots of restaurants and cafes nearby.
The only reason I’ve not given 5 stars is because the apartment could be quite noisy as it’s close to the stairs and you could hear a lot of noise from the street. There was also no curtain/blind in the bathroom window which you could manoeuvre around but feels like the experience would be more comfortable if it was there!
