The store is located inside the castle hotel by Lake Louise. If you're unsure, just ask the staff. The car was a Hyundai compact, but it comfortably fit four average-sized adults. The roads around Lake Louise, including to Emerald Lake and Moraine Lake, are in good condition. Renting a small car like this for touring around is actually very nice. The staff saw that my order already included full insurance, so they didn't try to sell us any additional insurance.
