Had a very pleasant stay at Antoine's! The pros: it's very spacious, with plenty of closet space. The neighbourhood is residential, but the subway (orange line) is just across the street, and you will be DT in about half an hour. The beds were comfy and the space was clean. Antoine was super fast in responding, and he even dropped off an umbrella after I asked for one. Check-in/out was extremely easy; I never had any issues with the passcode, and we were able to check in even earlier than usual. The Wifi was great and we never had any issues while working the whole week.
However, the building is older, so that comes with a few issues. The floor is creaky, and the shower area could be improved. The stairs in the front need work and are wobbly - if you're bigger or have large luggage, be careful. We ended up just using the back stairs every time as they're much sturdier. Other than these issues, the stay was very enjoyable!
