If I were you, I’d say The Rundlestone Lodge is a good mid-tier option in Banff — you get a lot of value: clean rooms, solid amenities, helpful staff, good location with some trade-offs. If your top priority is modern design or luxurious finishes, it falls a bit short there.
If I stayed, I’d be picky about which room (avoid noisy spots), check before booking that amenities I care about are working (AC, hot tub), and mentally budget for the “outdated but functional” style.
