The famous study overlooking Baker Street that has been portrayed in so many films over the years is located on the 1st floor above a flight of 17 steps. Visitors can sit in Mr Holmes’s armchair by the fireside to pose for photos, and enter his bedroom adjoining the study; but please bring your own pipe to smoke! His possessions are in their usual places: his deerstalker, magnifying glass, calabash pipe, violin, chemistry equipment, notebook, Persian slipper and disguises.
