Hotel in Calgary

[Van-rookie]

I am going to go to Calgary this weekend for a meeting at Macleod Trail S and have difficulty finding a nice, clean and cozy hotel room which is not too expensive. This is due to the grey cup.

Anyone know of a min 3 star hotel that is not too expensive (under $150) ? Doesn't have to be close to the meeting place. A suite with 2 beds and 1 sofabed, would be nice, but 2 separate rooms would be fine.

thanks
