I really do recommend this place for Sherlockians or fans of Sherlock, the tour guides are hilarious and very descriptive in telling the stories of Sherlock, its located in Baker Street What you should do before visiting it; (credidentials) Pre-book a ticket as the queue takes a very long period of time to get through and the people there can be absolute assholes at times when it comes to queing, take care of belongings and be sure to check out the Sherlock Statue located beside the subway
