Stayed in the Gopher Suite for 5 nights in August 2012. Being in the basement, we were worried it would be dark but it wasn't, and it actually meant our suite was shielded from the sun so it was great coming back to a cool and airy suite after a day in the sun.
Loved our stay at Banff Beaver Cabins and we were very sad to leave.
Great location for Banff National Park - within driving distance of most of the main walks, mountains and 'attractions' (e.g. hot springs).
Laura, the hostess, was really helpful giving us a map of Banff and a few hints of where we might want to go - enough information to get us started but also leaving us to discover a few things for ourselves which we really appreciated.
It was great to be able to come "home" to our own suite and collapse after a day of walking.
