Terrible Service, OK hotel
We stayed at the Sandman Calgary Airport in June 2006. The service was terrible - reception staff were completely useless and kept phoning in the night (after 9pm) to check our details. Rooms were fine and the restaurant, Moxie's, was nice but the staff, the price, and the middle-of-nowhere, scabby location let this place down. The grounds have been dug up so I assume construction is continuing on the site.
There are loads of nicer places, closer to the airport or to town, which we stayed in later. I wouldn't recommend the Sandman.
