I stayed for a single night at the Sheraton Suites in Aug, 2007, and was very happy with the property. Service from all staff was outstanding, including the front desk, concierge, and club lounge staff. I was also able to arrange for a private meeting area on short notice, and was very impressed with the staff and service.
Rooms are very comfortable and clean. There are many nearby restaurants, and the concierge was helpful in recommending some good options. Property is highly recommended for a stay in Calgary.
