Excellent location, close to all major conference venues/hotels in downtown area. a block behind the hotel is Montreal's major shopping district (St. catherine). Cross the road from the hotel, there is a office complex (IBM,etc.) where you can buy all sorts of food/snacks at reasonable price. But most importantly, the hotel is very clean, and quiet, and can't fault on anything (well, may be except the blanket on the bed isn't the best).

Decided to stay here because I found it on priceline.com for 66 dollars, then found for an extra 10 I could get my own bathroom. It's called the YWCA but don't be fooled, both sexes are welcome there. My room was small, clean and cheerful, pretty much what I was expecting. The hotel is a block away from St Catharines, very close to shopping, bars and restaurants of all kind.
I would recommend this place for business ar leisure, any trip where you are spending the majority of your time out and about.
My only complaint might be the tiny TV with poor reception - but really I wasn't in town to watch TV

The staff were friendly and the rooms clean and simple. The main downside of the hotel is its location in the downtown business district - rooms overlook a busy road, and if you want to walk into town, it's an unattractive 30 minute walk. We regretted not paying a little bit more to stay in or near the Plateau, which is the liveliest and prettiest bit of the city. But it's good value, and would be fine if you're happy to use your room as nothing more than a sleeping place and to take the metro everywhere. It has kitchen facilities, but don't plan on doing much cooking for yourself beyond reheating something in a microwave, as it lacks basic equipment like kitchen knives.

This place was by no means a bad hotel. The place was simple and tidy, the proximity to the town's hotspots was excellent, and the staff is courteous and accommodating. The amenities, however, are a bare minimum. If you don't mind this, book. The fact that the floors each had to share a bathroom/shower is very reminiscent of my college dorm days - I didn't mind this either. If you want to spend an extra $20-$30, however, you could find yourself with some of the amenities this hotel didn't have, including: a room with a view, coffee maker, hotel-owned parking, your own bathroom/shower, pool, gym, continental breakfast, and so on. Traveling with two young children, I would definitely recommend going the extra $30 next time.
