We had a great time in Montréal and staying at Alexandre and Caroline's apartment was perfect! It's exactly as described- very spacious, light and clean. The big patio is also a plus!
The neighborhood is great, too - there's not much traffic so it's quiet at night; grocery shops are about 10 minutes by foot and the Metro is just a few steps away, which makes getting around very easy. Private parking behind the apartment is possible - that's an additional plus!
We didn't meet Alexandre because either he or us were out and about, but communication and checking in and out was easy, too.
It's been perfect for us, that Alexandre made an earlier check in possible. We'd definitely stay there again!
