I'm heading to Calgary in a week or two, so you can share my hotel room and we can split the cost. It will be safe because I'm married and married men are absolutely no threat to young pilot girls....

Seriously though, besides the Port O' Call I like the Greenwood Inn and Hilton Garden Inn because they are close to the airport, but they are a bit pricey if you are trying to save some cash.
There is a Ramada close to the University that is relatively cheap and pretty safe. I think around 50 bucks a night. If you want to stick around the airport and go cheap...(although you said you want to be downtown) there is a Super 8 on Barlow Trail. I haven't stayed there myself but associates have and they said it was fine. Again about 50 bucks a night.
