Great location. Just next to the Metro and walking distance to lots of cool places and restaurants in Montreal (also walking distance to Old Montreal).
The window is cracked in one of the rooms that’s facing the big street so it was a bit concerning, especially since we have a small toddler. The window crack wasn’t notified so if you’re concerned about security, maybe contact the host first and ask if the window is fixed.
Otherwise, great location for your stay in Montreal.
