Lovely hotel in downtown Calgary. Stayed here for just one night. Front desk staff were extremely helpful and provided good recommendations for nearby restaurants. Room was spacious and clean. The hotel seemed to have a shortage of 2 queen beds, as I was told there were king rooms only upon check-in. Slight inconvenience, but they put us on the top floor with a lovely view, so no complaints. Bathroom shower is fantastic. My only com was that I think they need to replace the air filters, as after a few minutes in the room I had trouble breathing, but if you don't suffer from bad allergies, this is probably no big deal. Overall, the Marriot was a lovely place to stay in doCalgary!
