There never seems to be anybody at reception, so I don't know what the procedure is if you have a problem. They email you the code to the door so you need your smartphone with you. Also memory foam mattresses aren't for everybody, if you need a softer mattress look elsewhere.
I was pleasantly surprised upon arriving at this hotel, the other reviews mentioned the dread word "hostel" but what they meant was the building is drab and institutional, but the large rooms are fantastic at the price. They feature sound-proofing, a flat screen TV with satellite feed, a memory foam mattress and a mini-fridge. The location is also great, Lionel Groulx subway stop, with connections to the airport bus, is only one stop way and it's still only 20 minutes to downtown. There are few amenities in the area, but the hotel has two restaurants and there is a huge IGA food store a couple of blocks away.
