Perfect apt!
Check in: Terrific communication. Check in was very easy.
Building: The building is very safe and new. You need an outdoor code, followed by your fob entrance, followed by requiring the fob for the elevator and then of course the apt. lock itself. I didn't see or hear anyone else in the building while I was there.
Apartment: Exactly as advertised but with some nice surprises. As others have said, the apt. is spotless. Unlike other condo Airbnb's - this one is a step up. Lots of thoughtful touches. Keurig coffees, teas and chocolates. Shampoo if you forget yours. The mattress feels very new and the bedding is great. The kitchen is well equipped with new pots, glasses, cutlery, plates, knives, everything you need. There is no bathtub, but the shower is very modern with great pressure. The TV area is super comfortable. The TV itself is a Smart TV - while I prefer cable to Smart TVs this worked just fine. Lots of storage in the bedrooms and blackout curtains to keep the sun out for those who like to sleep in.
Neighbourhood: I lived in this area back in the 90's while going to school in Montreal and I really like it. It's close to Old Montreal, Ste. Catherine and all the shops, and two subway stations are pretty close. The train station is a 10-15 min walk. And of course, it is right in Chinatown by St. Laurent and St. Urbain. (A couple of my faves: Beijing Restaurant down the street has the best Canadian/Chinese food in Montreal. Orders are huge, delicious and the family that runs it are super nice and kind. Across the street from the condo is the best Chinese patisserie around. You aren't limited to your dim sum style baked goods (which are superb!), but there are lots of western baked goods too - croissants, pain au chocolat, cakes, etc. Put a coffee on and grab some pastries for your breakfast.
All in all, the best Montreal Airbnb I've stayed in - and I've stayed in quite a few!
