Really enjoyed my stay, which was brief. The location is amazing, the apartment has exactly what you need if you're looking to spend an extra day in Montreal either alone or with one person (I was alone). The check-in instructions were very clear, the place was as advertised and very clean, and the hosts were quick with responses during their advertised hours.
I did have a very minor plumbing issue, but again they were quick to respond, even though i was able to fix it myself. And I should point out, it was as likely user error as any problem with the apartment.
10/10, would stay again!
