Wonderful location! The apartment is located just a block off Ste. Catherine's street and on the edge of the Place de Spectacles neighborhood on one side and the Gay Village on the other. We took skates and loved the Esplanade Tranquille. And it was just a ten minute walk to Old Montreal.
The place was clean, quiet, and perfect for adventuring from. Good wifi, the kitchen had pots and pans and there was a washer/dryer. On the personal-professional AirBnb spectrum, this was on the professional side. The kids enjoyed the large screen and the floor mattresses.
A word about parking! There was plenty of on street parking on the weekend. You should be able to pay for it with just a credit card; this worked for me one day but not the other, so I downloaded the parking app and did it that way. There was a snow-related parking ban that went up sometime (orange signs which they attach to the regular street signage), so it is good to be on the lookout.
