We stayed at the renaissance hotel in Edmonton after a long flight for only 12hrs. Upon check into our room we found the hallway carpets dirty and full of stains. Our room had stains on the walls, trash on the floor and dirty base boards and grout. We requested to change rooms. While our second room was a slight improvement, it still had dirty walls and baseboards additionally the toilet was continuously running. The next morning we brought up our concerns to day staff and we were provided a very small discount on our room as an apology. We stayed at the hotel for the connivence of our flights but it was not worth the cost considering the condition of the rooms and the hotel.
