Hold on, 211B Baker Street is not a Sherlock Holmes museum anymore?
Now, I never knew there was a museum at 221B Baker Street. The only reference I have seen was in one of my books on Holmes and said that the Abbey National (NOT the Halifax, my mistake

) had its head office at 221 Baker Street and employed someone to answer all the letters which were delivered there addressed to Sherlock Holmes. Checking on Google, I see that the Abbey National HQ has been redeveloped as a block of luxury flats and that there is, indeed, a Sherlock Holmes museum at 221B. Thanks for mentioning it Panos.
