As far as who lived next door to him (such as in 220 Baker Street), it is not mentioned in the canonical stories by Sir Arthur Conan Doyle. Only does it say that he lives in a boarding house with two others - the first being Mrs. Hudson, the landlady, who lives on the lower (ground) floor and cooks and cleans the house, and the other being (naturally) Dr. John Watson, whose bedroom is on the third (second) floor. Holmes' room is on the second (first floor) as well as the men's shared sitting room.
The only other I can think of is Madame Tussaud's, which opened on the Baker Street Bazaar in 1835.
Mrs. Hudson; however, in the story "A Scandal in Bohemia", Holmes' landlady is named Mrs Turner:
"When Mrs. Turner has brought in the tray I will make it clear to you. Now," he said as he turned hungrily on the simple fare that our landlady had provided, ..."
Martha (only) is the name of the maid in the short story 'His Last Bow,' and some have speculated that this Martha and Mrs. Hudson are the same person. Anything further is outside the realm of the Sir Arthur Conan Doyle stories.
Martha Louise Hudson (née Sissons) was actually the landlady, renting 221B out to Sherlock Holmes and Dr John Watson. Martha lived in a flat in the same building.
Sherlock Holmes' real name is Sherlock Holmes.
