Stayed for one night at the Holiday Inn in Calgary. It was a nice spacious room. Staff were very friendly. I guess the only thing would be cleanliness of the room. You could see at the top of the shower it was dirty, and cleaning was not thoroughly done. Places where you would think no one would look, I saw the dirt in the corners and hard to reach places, especially in the bathroom. And I have a thing for clean bathrooms.
Other than cleanliness, the hotel was nicely done , spacious, staff were super friendly, and we enjoyed our stay. The breakfast could have been more maintained (i.e. they kept running out of bacon, and coffee.). And we went early before the rush.
