The museum is at 221B Baker Street, as depicted in the novel. The entrance is small but easy to find. Because there are people in police uniforms at the door, and a bunch of tourists in line. To buy tickets, in the souvenir shop near the entrance. First buy tickets, then queue up to enter the museum. When buying tickets, remember to take a light-colored introduction sheet, because this is the ticket. There are several floors in the museum. The second floor simulates Holmes'living room according to the description of the novel. You can take pictures with deer hats and pipe sitting on the table. The other layers are wax figures of some criminals in the novel. Not really. It's not a long visit, but it's still worth seeing.
