I was in town for a Flames game, and this was the most convenient location I could find to the Saddledome. Also just a couple of blocks from the bus for the airport, or if you arrive by bus, it's an easy (free) train ride from the Red Arrow bus station. Never felt unsafe walking around alone here.
Even though it was just me, they gave me the private room with enough room for 5 people, which was pretty nice. The breakfast is the usual cereal based option of a lot of hostels, so unless you're on a super tight budget, you'll probably want to get something elsewhere. There is a grocery store and a Tim Hortons just across the way, so you have some options nearby.
That being said, outside of groceries, Tim Horton's, and the Saddledome, there isn't a lot right around here to do, so keep that in mind when booking.
