Spent a long weekend in Montreal with my two little kids and had a wonderful stay at Nadia's. I would say that her place is nicer than the photos represent. Great neighborhood close to some very good restaurants and cafes and to Jean Talon Market, but not so close as to be too loud or busy (it was very quiet at night). Plenty of places within walking distance, but on bikes we were easily able to get all over the city.
Nadia was very easy to communicate with and left clear instructions. Her home was very cozy and felt more like staying at a close friend's place while they're away rather than at a sterile apartment that has one visitor after another. The place had everything we needed, including lots of books and toys that my little kids enjoyed. Wonderful backyard in which it was very nice to relax at night after kids' bedtime.
We parked for free on the street in front of the place without issue, so can't complain. The space to park in the back would have been a little tight, so I wouldn't quite rely on the parking on premises if this is something you'd absolutely need. If I'm nitpicking, the only other thing is that I wish the pillows were more supportive (though the bed itself was very comfortable).
Would definitely visit here again.
