The thing with hotel chains is that you pretty much know what you're getting. So this Best Western is no different. Nothing bad, nothing extraordinary. Just pretty good. Ditto with the price.
You can collect your Best Western points! =) Has a pool, and AAA/CAA/AMA discounts available too, though these two points are hardly unique in Banff.
Directions: On Banff Ave, head away from the river. Keep going around the bend. When the road straightens out, look for Marten street, and turn left. It's immediately on your right.
