I'm looking to book one of these Autograph Collection properties for six nights this Fall. The Bankside Hotel and St. Ermin's are close in price while the Montcalm East is less expensive. Any recommendations from anyone that has stayed at one, two or all of them. We're both have Platinum status with Bonvoy. Additionally, the London Marriott Canary Wharf is a great price. I've been to London before, but my partner hasn't. Would that location be a bad choice for a first time visitor?
