1. Cheap - low rates for rooms and everything is included (linens, towels, wi-fi, continental breakfast).
2. Amazing service - friendly, courteous, and knowledgeable.
3. Conveniently located - very easy to drive to via the Jacque-Cartier bridge and there's a cheap (12$/day) parking garage 100 meters down the road. Around the corner (again, less than 100 meters away!) is the Berri-UQAM metro (an important hub in the Montreal metro system).
4. Clean! - maids come through every day with fresh towels and to give every room a vacuum/swiffer.
I've stayed here twice and have no complaints. I'd stay here again without hesitation.
